Wah mod FAQ
21 Maj 11
If you have modified your Dunlop wah using one of the pages on this site and are experiencing problems, have a look here. I have added the most frequently asked questions, and will add new questions as they come up. First a couple of tips that are very useful when trouble-shooting your wah: — General trouble-shooting…
Modifying the MXR Phase 90 (M-101)
1 Jan 11
This post deals with the regular MXR Phase 90 (M-101). It does not apply to the EVH phaser, Custom Shop Script models (with and without LED), as they have a different type of circuit board. The 1974 Handwired model can be true bypassed with the help of this post. But for this excercise, make sure…
Modifying old Boss ACA pedals to PSA specs
23 Nov 10
As mentioned in the ACA vs PSA post, some of the older Boss pedals (those with an ”ACA” sticker by the adapter jack) won’t work right with a normal 9vDC power supply. Keeping them on a daisy chain supply, with power and signal cables connected to at least one normal (PSA) pedal makes them light…
The Stinkfoot TS-9 mod
18 Nov 10
Again, in the interest of lightening my work load, I’ve decided to post one of ”my” mods. The quotation marks are very justified in this case – the standard (stage 1 & 2) Tube Screamer mods I’ve done can hardly be called innovative, and ideas on what can be done to a Tube Screamer are…
How to add a killswitch to your guitar
17 Nov 10
We’ve all heard the effect, and possibly seen it too: a cool guitarist reaches for the pickup selector on his Les Paul, and starts to wiggle it back & forth to create a stuttering on/off sound. Trouble is, this only works on Les Pauls (and other guitars equipped with separate volume controls for the pickups).…
Vox V847-A and V845
15 Nov 10
This post deals with the newer Vox wah models. For a long time, Vox stuck to the circuit board layout of the ”old” Crybaby, and since there are already several sites out there that covers those, I haven’t bothered writing any instructions for them. Here’s a link to one of the best ones (go to…
The Stinkfoot wah mod
15 Nov 10
For a number of years now, I’ve been modifying wah pedals for friends and guitarists, mainly in and around Sweden. Lately, though, it has started becoming a bit of a chore, so in an effort to lighten the load I’ve decided to share that mod with the public. Most of the info is already shared…
Adding an LED to the GCB-95 Crybaby
15 Nov 10
Read this first… This page assumes you have already done the true bypass mod, or plan to do it at the same time as this mod. There is no way to add an LED to the stock Crybaby without replacing the switch, so you might as well make it true bypass while you’re at it.…
Changing the tone of the GCB-95 Crybaby
15 Nov 10
Also known as ”circuit mods”. This is a collection of changes you can make to the Crybaby circuit, to change its tone and response. Please note that this is not a list of my suggestions – in other words, I’m not suggesting you do all of the mods listed here. Some of them may not…
True bypass for the Dunlop GCB-95 Crybaby
15 Nov 10
This post is focused on how to modify the current production GCB-95 Crybaby for true bypass. It applies to all Dunlop wahs that use the GCB-95 circuit board, and that has the jacks mounted to said circuit board – in other words, the GCB-95 from 1990 onwards, the JH-1 (both the older ones and the…
