My last one: Traynor TS-60B Preamplifier.

It is similar to the TS-50B. The Preamp is well known as "Rusty Box". But this one comes with an extended 4-band EQ (switchable) and a DI-Out:

I dont use the Autorouter function. I draw the traces „by hand „

No, I am not an Electronic Engineer. I am a "Hydraulic" Engineer... (I dont know the exactly designation).

The holes for the rotary pots and the slots for the sliders were milled with a cnc milling machine.

I really like JohnK's pedals! As I saw his MonoBlock I got the Idea to use sliders instead of rotary pots.

Would you mind sharing the schematic? Where did you get the PCB produced? You have me all motivated. 

I used this schematic: Klick

I had the PCBs made locally. But you can made pcbs also online: Klick

No kit. I used the original schematics and created a pcb with eagle.

My new one:

It is a Traynor Mono Block II Preamp in pedal format.

Yes, my own PCB. Schematics from i-net. Sounds is a little bit different to the TransBoost.

Here is the enclosure:

Another overdrive with a transformator (test setup):

I am a big "fan" of Gallien-Krueger amps. That are my favourite amps. But I am also a big fan of tube amps. I've been testing various overdrives for twenty years. But I haven't found the perfect OD for myself yet. Recently I've been testing pedals with transformers. They could be the right way.

The 800RAIL sound good. A lot of OD-variations are possible. But it doesn't sound 100% like an 800RB.

I created a PCB in Eagle using existing schematics. The PCB was made by a local company.

My version of the TransBoost. An overdrive based on a transformer circuit.

My Version of a Fairfield Barbershop Clone:

First I engrave the font with a CNC milling machinen like this:

Then I use powder paint / powder coating. 

After that I take fine sand paper 320...

My version of a rog ginger:

My first one: sonnßeta

It is a Sunn Beat Bass Preamp in pedal format.

I used an existing schematic from dirtbox layouts and create a pcd that fits in a 1590B enclosure

Ooops, sorry. My mistake...
