Tools, Tones and Toys for Guitarists
I think this will be popular with quite a few people, especially those who want to get the most of their dirt pedals and fine tune the frequency response more effectively. I think this would go to make the perfect distortion pedal if you put your favourite dirt circuit with this in a dual effect … Read more
Request. A modded version of the Okko Diablo with pots replacing the onboard trimmers and scope for even more! This will give you an 8 knob version of the Diablo with the Presence and Bass controls external. If you’re feeling particularly brave you could even replace the trimmers on the booster to make an 11 … Read more
I’ve done a few layouts using this method, but thought it may be useful to include a little daughter board which will allow you to easily convert any existing positive ground effects to (daisy chainable) negative ground. Just de-solder the supply and ground wire from the existing board, and solder to this board, then take … Read more
There have been a few requests for tube based pedals and this is one I did previously. Based around JuanSolo’s 12V Boob Tube which is a Valvecaster variant, but here with a 33 – 40V supply via a charge pump. Make sure you choose appropriate rated capacitors for the voltage. This is verified and apparently … Read more
Request. This will allow you to use the better quality PNP germanium transistors, but keep a negative ground so it can be daisy chained with all you other NPN effects.
Requested. This is a modified version of the Xotic EP Booster, done by Fred Briggs and seen on his blog La Révolution Deux. Have a look around there and you’ll find some really interesting articles and information about many modern and classic effects. This version includes the voltage converter to provide 18V from a 9V … Read more
Runoffgroove’s stompbox emulation of the old Supro 16T amps and so potentially a good one for the BJF Honey Bee fans. This one needs 18V and so will require an appropriate power supply, or maybe make yourself a voltage converter like this one. Info from the website: Supro was a budget brand name for amplifiers … Read more
[Updated 4th July 2014 – correction to treble control resistors] Note: A new revision of the Klon layout has been done which is smaller and makes better use of the space, so if you want to build this I’d suggest using that layout instead which will also be easier to fit in a 1590B for … Read more
Layout updated. If you want to build this now I would suggest you build this version http://tagboardeffects.blogspot.com/2014/02/keeley-katana-boost-layout-rev-2.html Vero layout for this popular pedal with built in charge pump to provide the required 18V from a 9V supply. UPDATE (09-02-2012): The schematic that this layout was created from has been shown to be incorrect. In … Read more
This one needs an 18V supply, so use a dedicated supply, two batteries, or you could build up the 9V to 18V converter that I’ve posted here. Best results may be obtained if you heat shrink the LED and LDR together or at least wrap a bit of electricians tape round them both.
