I'm thinking about buying either a Univalve or a Bivalve. My questions are, having never heard either amp.....which should I get....are both punchy with plenty of low end.....are they quiet when played clean.....and finally how is the construction? I play a tele and looking for an amp that will have enough volume for small clubs with a decent amount of headroom. I understand with a lot of gain these amps can be a bit noisy, but if you play them clean does the noise level clean up? Thanks for the opinions and suggestions!
