RAH tone mods

[Plaidesaurus]

I'm going to build a second RAH. Love the first one but I wouldn't mind ditching some of the high end on the treble. I'm currently rolling it most all the way back. Maybe I need more low end instead. Any suggestions for parts swaps?

This pedal uses a TMB tone stack, so the knobs are all interactive. Here's some info on how it works to help guide you in tweaking: http://www.kldguitar.com/Navigation/Resource/Article?name=How-The-Guitar-Amp-Tone-Stack-Works.html

I just building the Apollo Mk2 from Aion which is a RAH clone too.
I guess you can finetune the lows with the first cap c1 3.3nF. This is indeed a bit like a treble booster. You can up this cap to 22nF or 47nF. If you use pin sockets, you are able to try several values.

Another thought if you like it tuneable just use the input section of the catalinbread naga viper (pedalpcb dragons breath) with two caps (3.3 and 68 nF)


I would not fool around with the tone stack, this is an exact copy of a vintage Hiwatt DR 103, it makes this signature sound,

This is a solid idea - I’ve tried it and it sounds very good indeed.

Sounds great, guys. Thanks for all the good feedback.

You could also tack on Mark Hammer's Stupidly Wonderful Tone Circuit ala AMZ.

Run the SWTC just before the volume control to tame some highs, no messing with the core integrity of the circuit.
