wrap the speaker cab with memory foam
SC20 in 5 watt mode?
800s and late 70's JMPs seem to be matched to the G12-65.
Brite cap and peaker cap mods?
Hi, what do you do with your amp? Home play, gigs or a mix? Do you have a home studio setup? Sorry i don't know your context. I notice peoples ears change with exposure/degradation, some get less sensitive to the highs and others can't be in the room with them. I can't hardly watch some of my favorite youtube players because they've gone too far to the high side. Maybe they're just used to a band mix, but that's not pleasant at home, in my opinion. I can't take the harsh highs.
EQ in the loop
Mod the amp, remove treble bypass caps and or bleed off treble with caps.
Put your cab in a closet and mic it, then use your monitors or headphones.
Replace your 4x12 with a 1x12 cab (like a 150W Redback) or ad a switch so you can run just one speaker vs 4 (with appropriate wattage speaker) If you were careful, a 97db Creamback 65w.
Reactive load with built in IR and run to monitors.
Get a different amp
Mic & cab in the closet is my current favorite. Suhr Reactive Load IR into DAW with reverb if I need to be quiet.
I know some would never mod a $3000 amp or a vintage, I understand but if your not enjoying it, what's the sense? I'd mod Hendrix's Super Lead if that's what I wanted,....actually, I'd sell it.
2203x has a treble knob, a presence knob, an fx loop which means you can put an EQ there if you like, and the guitar should have a treble knob. How with all these treble reduction circuits can this amp be too bright?
Maybe need to approach this from a different perspective and or possibly get rid of the mods and put it back to stock.
Hi. Search "compensated earplugs" on google. Etymotic, Vic Firth, several brands of the same thing. Pretty clever gadget, attenuates 20 dB or so without cutting the high end. Yo just hear the same, but 20 dB (a LOT) quieter. I use it all the time in a loud band, with excelent results.
They're OK - but if you look at the frequency curves - there's always some extra high frequency attenuation even with so-called "musician's ear-plugs".....
It could be the guitar too, unless it's that way with every guitar. A2 magnets in the pickups or if running high output pickups some thing like a DMZ Tone Zone could help a bright guitar. 800's are bright amps but it should be tamable without ear plugs I would think. But with a bright guitar maybe not without deadening the harmonics too much.
Put a HUGE snubber cap on v1, or at the "fizz cap" on the PI.
Buy dark speakers like the Emi. Swampthang or Delta Pro 12A.
Tell me more...what value cap? You say on v1...where to where? Thanks!
Add beam blockers to
And that's their intended use, in a loud band or concert setting. I don't see the need to use earplugs when playing at home, when you have total control of the environment and volume, but hey, that's just me.
Most 2204/2203's have a grid to plate cap on v1, which if I remember is like 1000pF?
A "snubber cap" is used to control oscillations. But one of the side effects if you make that cap too large, is that it rolls of high end.
The typical "fizz cap" at the PI (c18) is usually 47pf, and a lot of modders increase this to 100-120pf.
I've experimented with much larger values with varying degrees of success.
Forget modding your amp just to get rid of some unwanted high end . It’s all about speaker type , position and volume of course . When I say speaker position I’m talking in relation to your head . If you’re for example standing fairly close up to your say 2x12 horizontal speaker cab and it’s on the floor the high end will completely pass you and sound dull . If you place the speaker cab with exactly the same amp settings on a table or worktop the sound will instantly be loads brighter . If you then say sit on a chair so the speaker is at about face height it will probably be painful in the high end . Hope this makes sense , give it a try mate .
This by the way is also why I believe to get the full balanced spectrum of high and low end and mids you need to stand in front of a full stack .
