I must say it sounds sweet true my tube amps. Not as harsh as stock ds-1 and it has better mids/bottom end now.

I am surprised I didn't screw it up though I ran into problems with my soldering gun not melting the solders initially.

Hope I didn't wreck some components like diodes and resistors due to heat exposure but I do notice the ds-1 is not as noisy as it used to be after modding.
