I think I read something about it being True Bypass. Is this correct? PixelBurst Active member. Joined Apr 11, Messages 4, Supporting Membership. Forums New posts Trending Search forums.

DR5Guy Member.

Messages It seems there is no clear consensus if the Q is true bypass or not. Some source claim it is not, others say only revision F and later are. Last edited: Jun 23, Messages 14, Remove the battery.

Before , all Dunlop wah pedals had wires between the jacks and the pcb. In mid Dunlop changed the pcb design, and started soldering the jacks directly on to the circuit boards. The earlier type of pedal is quite easy to modify for true bypass, while the ones with circuit board-mounted jacks are a little harder.

The current revision is Rev I, which has a different circuit layout around the inductor which is the red Fasel reissue, btw. Other than that, it looks much like the Rev G and H wahs that has been running since mid there is actually no real difference between G and H, other than the colour of the circuit board. Rev E units have a slightly different layout, and have a special section below.

I do have a page on the newest Vox VA, though. It is a little confusing, but the buffer circuit is a separate circuit that has been added to the existing wah circuit. Take the back plate off the wah by removing the 4 rubber feet and remove the battery. Sliding it downwards away from the pot usually works for me. Now, find out what revision your pedal is. Later models Rev H and I have a written revision letter in the top right corner, while others have the revision identifier etched on the solder side of the board.

With the pcb out, take a good look at it and compare it to the one in the pics to the right. The buffer components are the ones crossed over with red X:s. It should be six components in all including the transistor. Cut yourself two pieces of wire thin, flexible multi-strand type that are long enough to easily reach the switch from the pcb.
