Red label, thanks SO much for turning me on to these!!! I ordered 2 and got them yesterday. (was at work) So, I tried em today and they work great! I tried running one and both in a chain on both my Tweaker and JCM800. The tone is colored only EVER so Slightly with both going. But that really cuts down the volume.. Im really enjoying my JCM more cuz I can get the dynamics out of it now and its not fizzy like it can be turned so low.. Plus the response to the vol control on the guitar is awesome. Up and its crunch crunch scream!! down, its warm and sweet.. Plus, I can get great harmonic squeals. Basically Ive got the good tone of the amp in the sweet zone, but my kids can hear the tv in the other room..
Im stoked!! Plus, they are very inexpensive, AND dont require batteries or a plug in. Thanks again!
