Runoffgroove Thunderbird: adjust mids?

[Bucksears]

I've got the board populated for the ROG Thunderbird and will be wiring it up soon, hopefully this weekend.

Looking at the schematic on the ROG site, they mention that the tonestack is fixed. If I wanted a way to control the midrange on the circuit, could I swap out the 1.5K resistor to ground and replace it with a 2K or 5K pot?
Given the high/low cut/boosts that are present elsewhere in the circuit, I didn't know if this would make a difference.

As you say, there is a lot of other tone circuitry involved. You may find that simply adjusting the highs and lows pots gives you the tone you're looking for. The Tone control would have a bigger impact, imo, as is sets the mids up for the 2nd and 3rd amp stages.

That being said, you do have a lot of tone-shaping opportunities with changing cap values and diode types, but Thunderbird is painstakingly modeled after a specific Marshall amp, so I would build it stock at first and then see if it really needs tweaking.

Happy building!

Yeah, getting ahead of myself - just curious about that before I was planning an enclosure.
thx

When you say "adjust mids", do you mean enhance it, tame it, have cut/boost, move the focus of boost/cut around?

Makes a differences in terms of strategy to adopt.
