Hey man! I have a true bypass looper and have a Wampler Clean Buffer in one of my loops that's always on. I have 25 feet of cable into the board and 25 feet into my guitar so even though everything is going through the TB looper there's still some signal degradation. Go on YouTube and search Divided by 13 RPB and you'll see my video where I shortly demonstrate that.
I used to run my ehx hog in its own keeley tb loop to avoid tone loss
a few weeks ago I removed it . got sick of the extra switch to deal with gigging. Its fine messing around but when your tryin to move around and put on a show on stage every extra switch is another thing to think about.I'd rather have a tiny bit of tone colouration and make life easier on stage these days
I just use a buffer. I have a TB looper that I use for a few pedals that have some really bad tonal coloration or suck (I'm looking at you Whammy IV) but other wise, I honestly think just having a good buffer is the best. Again, unless you have a pedal that does funky stuff to your signal, like a vintage Univibe pr something, a good buffer is probably best. Because some of the pedals I use have buffers in them (Maxon AD999 delay for example) I might end up with one at the beginning and one at the end of my signal chain. But I have no issues with that. Sounds fine...
I have considered and Octaswicth. But thats more for presets of 8 different pedal set-ups to avoid the tap dance, more than its about using it as a TB loop.
I had a five loop strip, too many cable and too much board space. Maybe a loop-master clean dirty switcher is a better compromise with a rythym and lead loop. For a buffer, I just like to have an always-on boost like the Caroline Icarus. If you have any pedal on all the time, unless you have a dozen pedals, I don't think a buffer is necessary.
really, it depends on what you want to do - if you can access everything easily and don't want to run a cable to and from every pedal then getting a small buffer or something included would be the the way to go.
