I just recently purchased a Traynor YCS100H and a Hartke GH412A 4x12 cab. Now, the amp for one sounds absolutely beautiful and the distortion is great, but my problem is that I am not getting good squeals out of it. Now, would this be the cabinet or is it just because I need to turn the amp up louder? When I turn my OD on I, of course, get great squeals and harmonics. So is this a common issue with amps or am I missing something. Oh, and no flaming. I'm still new to tube amps and all I'm wanting is some advice.
