Without using any buffered pedals or stand alone buffers, I've found that relay switchers change and degrade tone more than regular 3PDT stomp switches. Relay switchers I've tried include Lehle, Wobo, Axxess Electronics and a few others. I ask because I am considering getting a Musicomlab, Gigrig or other programmable looper and I am hesitant. I don't like to use buffers with my clean tone and have been using a loop-master (3PDT type) for some time as I believe it is the lesser of the evils. The loop master is the most transparent solution I've tried but I have out grown it and need more loops. The programmable relay loopers are appealing but not if all relays alter tone in the same way. Have you found that relay switchers/loopers alter your tone more than standard true bypass 3PDT stomp switches?
