    Finally took my Boss SD-1 back out last night. Hot dang!! Remembering that a Boss SD-1 and a Marshall were meant to be. Makes my HSS Strat sound phenomenal. Tight, crunchy, and very fluid-y all in one. Notes are very articulate, ring and sing. Copping some HUGE Lifeson tones without even trying ( TC Nova Repeater and Boss CE-20). My MXR 10 Band might have to sit this one out.

    Edit: 10 Band EQ now sits in the loop where it now adds back in the Bass from clean boosting the front with the SD-1. Tight, thick, creamy sustain. Y'all have to try it sometime!

    Boss SD-1 fans around here??

    I've had mine for over 20 years now. It's been on and off my board throughout the years. I just got it back from my brother not too long ago and put it back on my board. I loaned it to him for a while and I started missing it lol. It just sings with Marshall's like you said. Everyone should own one. They're not expensive and they sound awesome.

    @lespaul339 Right on! Have you tried the WAZA version yet? Mine is Taiwanese and I don't have experience with a MIJ version either. So worth it for the price and what they do. Lots of ODs stashed but I always come back to this one. Still love the RAT as well.

    I have not tried the WAZA version. I actually haven't tried any of the WAZA pedals at all yet.

    This is not unlike going onto a forum for lesbians and asking "Any flannel fans around here??" :)

    They are wayyyyy overrated. I have owned two and both had the worst buffers and average tone at best (I like my DD-7 way better than the Waza delay and the best thing about the waza chorus is the vibrato mode). I have already sold the delay off and the chorus is for sale right now(they cost so much initially, they rarely get used, and no-one wants to pay the cost for them used...save your money and get good true bypass pedals or rack units).

    Thanks man!

    LOL well..... My board never used to have that many pedals on it. When I played live I kept it pretty simple. But since I quit gigging, I stopped looking at my board as a live rig, and started looking at it as a recording board. So it has all the tools I need to get whatever sound out of it that I want. I know it's kind of crazy haha

    marshall and a sd-1 are the perfect match... make it even better,,,put a xotic ep pre booster or even better ...clinch ep pre in front of it...unreal tone...thats all i need

    I keep meaning to get one. Lots of pedals come along, but sometimes the common ones that are proven are the best.

    Not sure how authoritative it is, but I found this on The Gear Page:

    The following is copied and pasted from a member on tdpri named 11 gauge which sums the topic up pretty well.

    "The OD-1 to SD-1 evolution wasn't really linear.

    The OD-1 made its debut in November of '77. It went through a lot of revisions with different op amps and such. But by February of '81 the SD-1 was released as an improvement to the "final evolution" of the OD-1. Boss felt that a tone circuit was needed, so one was added.

    ...By extension of that, the SD-1 is primarily a final rev. OD-1 with the tone circuit. Boss had gone to the same 4558 chip as the TS with the final OD-1D's and all of the OD-1E's. Well, TS freaks will argue that it's different because Boss used the TL4558P, uP4558C, and C4558C along with the "real" JRC4558D.

    IMO, most differences that people hear between the OD-1 and SD-1 are with the OD-1A to OD-1B series, which had the most circuit differences, and used the RC3404ADB and uPC4741C op amps. Boss had NO issues sourcing their parts from the lowest bid source, which meant NEC, TI, or whomever was cheaper than JRC! This is witnessed with the DS-1 to this day, as well as the numerous Boss pedals that use the "dreaded" L series op amps (8 pins in line).

    The SD-1 has remained just about the same as it was in '81. The op amp now has two D's, but that just means dual layer, or quieter operation, slightly more gain as a result (negligible IMO, really). Even when Boss opened their factory in Taiwan, the SD-1 stayed the same.

    The OD-3 has nothing in common with the OD-1. It is the offspring of the OD-2. The OD-2 was a radical departure in stompbox design, at least for Boss. It has NO op amps at all. It uses a configuration of transistors to simulate a crude op amp - the result is more favorable for use in stompboxes since it can't stay linear like a true op amp can - you get more inherent asymmetrical clipping! The downside is that it requires funky biasing and the circuit is complex in comparison to an 8 pin chip. In the case of the OD-2, the "turbo" mode cut the voltage down to UNDER 6VDC, which is why it distorts so readily. The array of transistors requires a pair of jFET's with a PNP bipolar transistor on the output.

    ...The normal mode with the OD-2 is basically a single gain stage with those three transistors, and the same clipping diode arrangement as the SD-1 in the negative feedback loop of the array. It runs at around 8VDC IIRC. The turbo mode uses a PAIR of those gain stages at lower supply voltage with NO clipping diodes. Both "meet" at the same tone circuit, which is identical to the BD-2.

    The BD-2 is the ancestor to the OD-2. It basically takes the turbo mode and does the following things:

    - voltage goes up to 8VDC
    - first gain stage is set up like a SD-1, cutting all the bass out
    - "fixed tone stack" that simulates BF/SF amp comes after first gain stage
    - 4 clipping diodes to ground follow the fixed tone circuit
    - second gain stage is like first, but doesn't cut bass like the SD-1
    - a dual ganged 250K pot controls BOTH gain stages (one was fixed in the OD-2's turbo mode)
    - there is a mild filter to remove some bass AND treble after the 2nd gain stage
    - same tone stack as OD-2 is next in circuit
    - an op amp boost stage comes AFTER the level control, and has a fixed ACTIVE bass boost

    The OD-3 is the final offspring (thus far) and differs from the BD-2 in the following ways:

    - true 9VDC operation
    - first gain stage is unity gain with a fixed "notch" filter (cut before boost)
    - second gain stage is like the ones in OD-2/BD-2, but it has clipping diodes before and after it
    - third gain stage is a "discrete class A" stage with clipping diodes
    - fourth and fifth stages are op amp ACTIVE EQ shaping - they are like a hardwired Baxandall tone circuit (bass and treble)
    - tone circuit like in OD-2/BD-2 comes next, but has modified component values (for better bass/treble balance)
    - level control is last, with no post boost op amp like BD-2

    ...The OD-3 gives asymmetric clipping with the most headroom, and the best staging of EQ filtering. There is no funky tone circuitry, all gain stages that clip have diodes to clamp them nicely, and the op amp portion is "encapsulated" within the circuit."

    I have had an SD1 for over 5 years now, and it is as reliable as always, and tightens up the overall drive of both of my rigs, and I can’t see tossing it for another.

    I'm a big fan of the SD-1. They are plentiful and cheap to get and sound great. It has a little bit more noise but also more gain than my TS-7 tubescreamer, which is also a little smoother. The two compliment each other nicely and consider I paid less for the pair than a used OCD, BD2, OD3, TS9 etc it's pretty tough to beat.

    I also haven't tried the wazacraft version. Maybe it's a marketing failure, or maybe I need to read more about it, but I don't really get the point of it exactly.

    I really screwed up and SHOULDVE bought an SD-1 but instead bought a Joyo Ultimate Drive. The JOYO is a fine pedal for what it does and the way I use it, it is merely an overdrive without adding almost nothing on its gain section. But since im using it like this, an SD-1 was just a few bucks more and probably made more sense honestly. But its working so im not gonna dwell on it too much. Really would like to add a 10band eq in there and a noise suppressor and id be a lot happier

    @Clockworkmike : The THREE most crucial pedals on my board in the exact order.

    1- BOSS SD-1
    2- MXR 10 Band M108s
    3- ISP Decimator

    Right there is SO much of my tone shaping on how I get the grit without the super high top and fizz.

    I have a SD-1 Waza. My understanding is the components are upgraded over the standard. It seems quieter and the custom mode has more thump and gain. I like it and feel it was worth the extra cost. It pushes my SV20H like one would expect.

    I also have an original OD-1 from the 70s. Like mentioned above the tones are very familiar.

    Great post man.

    Very much appreciated, real cool to share your time and knowledge with us. Definitely explained some things I was hearing, or thought I was hearing with my pedals.
