    Finished up a build today: Throbak Strange Master. I made it with selectible 2N2222 and 2N3904 SI, and a Tone control. The other TB I have is a Dallas Range Master clone made by GMR Spares. Here are my initial observations:

    Strange Master
    - less squeak
    - full mids
    - rolled highs
    - mid-gain
    - 5n -> B100k pot

    BC Dallas
    - more squeak
    - scooped mids
    - highs that bite
    - high-gain
    - 4n7 / 7n7 / 10n8 -> DPDT sw

    Both are great boosters! Strangely enough my Maxon ST-9Pro can get pretty close to the SM. Once I acquire a Germanium BJT its on!

    Very nice ! I have the schematic for the Strangemaster, gotta give it a go one of these days. Treble boosters are fun with NMV amps.

    I built a couple circuits yesterday (Ampeg Scrambler, which is an octafuzz, and rebuilt my RAT as a RAT2/"white face" version) while waiting for my Tayda order to be finally delivered after spending 3 weeks in customs limbo, and actually completing a couple builds...

    So you mod upon the Grundy pedal design and the other is a stock clone. I like your transistor option in your build.
    I have the JMI RM TB and a Jauernig Luxury Drive TB that sound very good with early Marshall's.

    Hopefully your Tayda order will clear soon!

    looks like lots of fun!

    I've really enjoyed playing with a treble booster and really enjoy it's rather unique way about boosting. As mentioned before I think these really shine when pushing a NMV amp over the edge, it can be some of the meanest sounding distortion... The richness in harmonics are a wonderland to play in and altered tone of guitar is very inspiring imho.

    Couldn't have said it better. I just finished tweaking my TSL's drive channels and would you know what I used to certify its sonic correctness? These two wonderful pedals. (Psst, see my updated thread all you TSL owners out there!)

    That's exactly what I do. When I go out to check out an amp, I bring my beano boost with me. If my beano boost doesn't like the amp, we go home alone.

    Did some fine tuning on these today:

    BC Dallas
    - 4n7 / 7n5 / 9n9 (largest = balanced mids and lows)

    Strange Master
    - B10k + 13k (more boost)
    - 470k + 22k (492k = more gain in bias)
    - 5n > 4n8 (more highs)
