Why two versions from the same pedal, hand wired and pcb?

We first started making pedals by hand and after some time we found out that it is an expensive way to do pedals and almost no-one else made the pedals like that. So we did redesign our pedals so that there are more components on the board and the pedals are faster to build.

The quality is as good on the pcb pedals as the hand wired. Actually there is a small hand laid pcb also on the hand wired pedal, but all the knobs, pots. Jacks, dc-plug, foot switch … are wired by hand.
We thought we would stop making the hand wired pedals, but as there is ever growing demand for these, we ar still making also the hand wired versions of the pedals.

Is my pedal hand wired or pcb pedal?

Easiest way to see it is to open the bottom plate of your pedal. If you see wires, then it is hand wired, if you see a pcb board, the pedal is pcb-version.

You can also tell the difference without opening the pedal, as the dc-plug jack is different on these two pedals. The pcb-pedal has a square hole and the dc-plug is inside the pedal. On the hand wired the dc-plug is round and it is partly outside of the pedal.

Do the hand wired and pcb pedals sound the same?

Yes, pretty much they do, there can be minor differences, but the schematics are the same.
Except for these pedals:
Mighty Red Distortion: The pcb-pedal has more output (is louder), people asked for it, so we made it.
Forest Green Compressor: The pcb version has a different function on the tone-pot, it is more traditional. The pcb-pedal has also less compression and is bit more transparent, this seems to be more popular for guitar players, bass-players and those who need heavy compression love the hand wired one.
Tiny Orange Phaser: On hand wired pedal there is a Balance pot and that has been bit confusing to use for some people. The pcb-pedal has a switch for two Phase-tones and a Mix knob.

My pedal does not say BJF design on it

At first when we made all by hand, we did print BJF-design on top of the pedal. Then we started to make same pedals as pcb-versions and soon run into problem that people could not tell if the pedal is hand wired or pcb one. So we started to print the text ”Hand wired” on the hand wired pedals and nothing on the pcb pedals. It would we confusing to print the BJF on those pedals only.
As all the pedals are BJF-design anyway, it was not nessessary to print it. We needed that space for the hand wired information.

If the pedal does say ”Hand Wired” it is hand wired, if there is no printing, it is always a pcb-pedal. If it reads ”BJF-design” the pedal can be either older hand wired or earlier pcb pedal (check the ”Is my pedal hand wired or pcb pedal?” question).

Where can I buy the Golden Cello or ”1” Pedal?

Those two pedals are Guitar Center exclusive pedals and only available from Guitar Center stores and Guitar Center and Musicians Friend webstores. Don’t worry, they do sell all around the world.
”Why did you do such exclusive pedals?”
I could say that they made us an offer we could not refuse, but really it was a custom order from them. We would have never made those pedals if the Guitar Center had not come to us with the idea and an order for them.

I found a Mad Professor Deep Blue Delay for sale on a website in China for $50, is this a real Mad Professor pedal?

No it is not, that is a counterfeit, you can’t never find a real Mad Professor pedal for that price. You can tell from the printing and how the pots are placed that is it not a real deal. Also on this fake pedal the DC-jack is on left side, we always place it on the right side.
The fake pedal has also polarity on top of the pedal. We do not make pedals in China, so there is no possibility for a ”leak” of the real thing.

Where can I get my Mad Professor pedal fixed?

Please contact fist your local dealer. We have a policy to give a new pedal to replace your defective one if the pedal is under warranty. If you need help, please contact tech@mpamp.com
