I messed about trying different buffers in different position's of the chain, I had some pleasing results but over all true bypass just sounds better to my ear especially where the wah and fuzz are concerned.
I then realised that the MXR pedals were sucking tone. What a bummer! This realy hacked me off since I had a 90's Phase 90 and then forked out more cash for the 74 RI under the impression it was true bypass. Like all the other pedals these company's have ripped me off with over the years promising some major improvement," Oh yeah this time we've realy done it it's the real deal ":

Worst bit is the pedal sounds gorgous when its on. For the sake of a switch that can't add that much more to the cost of it... and I'd willingly pay, why on earth would I want a pedal that sucks tone. I know the originals did but maybe that's one modern improvement that we might actually benefit from for once. I'm not brave enough to go in there and start hacking it up to try fix it. So it's got to go!
I then realised the tuner, although it's not in the effects chain it's in paralelle and the buffer was still messing with the tone and the same with the volume pedal. So that's gotta go! The delay is the only tone sucker there but with everything else removed it's impact is minimal and besides I usualy have it on most of the time anyway.
So I moved the Wah. Now it run's Guitar, Fuzz, Beano Boost, Wah, TS808, Delay. Man what a difference! It sounds great. The Fuzz and the Wah sound amazing, they seem to have more frequencies to play with.
Troubble is now I've got no stage tuner and no way of killing the signal with out turning the amp down to change guitars. And I can't use the Phase 90. So I'm wondering if any one has tryed the Voodoo Lab pedal switcher or a similar system, any opinions, sugestions? I realy don't want to fork out more cash on something that could turn out to be garbage.
