I will probably restore this since I do not need any more gain on the clean channel and I am not sure I like the change in tone. And it seems to also affect the voicing a bit since it includes C8 and R9 in the feedback loop (probably to compensate for adding R5 on the first stage). It gives another boost in gain on the cleans that is immediately audible as extra noise. I have tried this but I am not sold on it.
The top right is not connected to anything, and the bottom left is no longer used since we removed the LEDs. The panel now looks much better The switch fits only if it's mounted on its side so that it flips horizontally. Replace the plastic boost switch with a DPDT toggle switch. Perhaps it makes sense to experiment with different values and types here to suit your taste, but without it, you get a nice percussive and super-rich sound that is almost JazzChorus-like. Something especially evident in harmonics and pick attack. Without it, when the boost is on, the sound gets a bit harsh. It rounds the sound a lot, and it kills lots of clarity. This cap acts as a low-pass filter on the final stage. This is super easy and very straightforward. Add a 1/4 jack to allow connection to a CAB. When you engage the boost, the amp still goes loud fast, but you get some more volume resolution than before. The difference is more evident without the boost on. Change the linear volume pot P4 to one with an audio taper. This brings me to my second recommended mod. The only issue with it is that when the boost is on and the gain is set high, the amp is VERY loud. Just snip the LEDs and you immediately get rid of that "bees in a can" sound when the boost is on.

This is the first mod that anyone should do. Ssguitar and tdpri forums have much useful info.
So here is the list of my TODO stuff, gathering info from around the internet, plus results so far. I do not expect it to clip or sound like a tube amp on its own, but it can sure sound awesome with pedals. My goal is to have a nice super-clean platform to use with my pedals.

Plus it's a DIYer's dream, being a full old-school circuit with a transformer PSU and all through-hole parts.

With a few mods and a cab it sounds very nice. That's my second ongoing small guitar amp project after the Fender Champion 40.
