You mean top jacks?

In addition to what has already been listed:

Fuzzrocious
Smallsound/Bigsound (some)
Aguilar
DMB Pedals

 

Here's a former version of my board, the entire bottom row is top jacks!

 

Fuzzrocious BDPG!

 

It's an overdrive.

 

T-Rex pedals but they may be too big.

 

Yeah it's essentially an overdrive...officially he called it a dirty preamp. There is no clean from a BDPG! What makes it different is the tone stack. With one knob you can go from thin, bright and spitty to fat and juicy dubby thickness with no top end just with the tone knob. You can use it to fatten up anything. They are no longer made though.

 

They are loosely based on the Submarine right?

 

Looks candy-orange on my monitor – yummy colour.
