It's a Tonebender mk1 with larger input and output caps for more bass, also 2 x 22uf electrolytics like the hurst schem, and a 1.2m output resistor for a bit more output.
Input cap = 0.1uf Wima (old)
Output cap = 0.53uf Panasonic (modern)
Tagboard construction with fixed 8.2k bias, OC71, OC73, and OC45 transistors in there.
The transistors were checked for gain and leakage, checked again in the circuit temporarily, then soldered into the circuit for eternity!
Old mini chicken head knobs, hand sanded top surface with decal labelling and clearcoat.
Full warranty included.

And here is one with the Doombender mk1 alongside a wooden JMI mk1, DB 1st then JMI 2nd and so on for each chord/riff/phrase.Download: http://www.happyrobotmusic.co.uk/mp3/pedals/doombender_vs_wood_jmi.mp3
Both have the attack on full, the jmi has the volume on full, the DB has the volume halfway. To my ears the Doombender has more sustain, less gating, less sizzle, and more output, anyway judge for yourself!And lastly here's one done with a bass guitar, however its recorded using a small guitar practice amp i'm afraid! starts off with the attack turned down then up, then all over the shop.

if its not gone by friday I will have to resort to Ebay.
I'm absolutely NOT taking any orders on MK1s at present so here is a good chance to get one from me.
any questions please ask.
