Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter

Roger Mayer Mongfire
Hybrid switchable Roger Mayer Mongoose and Spitfire
This is a great idea. So there is the standard 3PDT bypass switch, and then a separate 3PDT to switch between the two? Would it be possible to rig it up to have an led or two to show which "mode" it is in? Or put in on a toggle switch instead maybe?
I'd had in mind a 3PDT toggle when I was doing the layout, they're pretty cheap on eBay now. Footswitchable may be preferable to some people for quick switching on the fly, but you'd need a 4pdt switch for LED indication.
I built this one and can barely tell the difference between the two fuzzes. Should I start troubleshooting it or are the two really that close in sound? FWIW, it sounds great as is but the switch appears to serve no purpose.
I agree. I could not hear any difference. I suspect that the ic and or transistor difference is where it would become apparent. To save space and material I am jumping the appropriate points to go full time spitfire.
Nice one!
ReplyDeleteI can also use the LM308 as opamp?
ReplyDeleteI don't see why not. One has a 308, the other has a 301 so you've just got to choose which one you want to use out of the two.
DeleteVerified!
ReplyDeleteThanks again Mark,
Chris
Excellent, cheers Chris

DeleteAlright, I'm thinking about trying this one out. I'll probably just stick to the 3PDT's.
DeleteAm I correct in saying that the Vol. 3 lug has TWO wires coming to it - one from the board ("Vol. 3") and one from the switch ("Sw2")?
ReplyDeleteHas anyone tried putting the LM308 in this build?
Tx,

Well, I haven't built this but that's what it says. :)
DeleteOne from the board and one from sw2, to vol3.
