Tonezilla mkii

image

I just rebuilt a friends tone bender mkii i gave him almost 2 years ago. Realised component values were all over the place, my mistakes, crossing oc81d and oc75 schems it seems.. ah beer days..
Now sober as a court jury, i wrote it all down. I made some sort of magic there, the pedal is one of the most powerful mkii i ever made, most likely due to my errors.
The original had carbon comps/ carbon film resistors and dubilier, philips electros, wima caps. This has wima, roe caps and carbon film/metal film resistors but still sounds amazing.
Since he gigs a lot, i had a mission to build it like the proverbial tank.. and to shuffle the controls a bit: he wanted to have the q3 bias out in lieu of the attack pot, that he uses maxed all the time (it now sits inside as a trimmer).
I messed up the decal a bit, hope he wont mind…

OC81D Tone Bender mk ii build

Bought these trannies more than one year ago. Finally got around to build it. Sounding GREAT. Very violin like tails, good smooth fuzz.
Thanks Dr. Nomis @ freestompboxes for keeping an open mind over these new dsi transistors.. and helping me with my build!
