Hi there, I am looking for a new amp. Currently I play an H&k tubemeister 36 through either a H&K 1 x 12 or a Marshall 4 x 12. Normally either a les Paul standard or a gretsch white falcon. The music is originals that is a mix overdriven and delay sounds all originating from a pedal board (ie not using the amp drive). When playing small gigs I much prefer the sound of the Marshall quad but find I am running out of headroom. With the H&K 1 x 12 I run the volume at 40% and it is plenty loud. With the quad speakers I am running the amp at 75% of max volume and getting obvious clipping on the clean channel. That can of course be a desirable sound but it is not something that I want with some of the delays I am running. So I feel like I need an amp with more headroom. It also needs to play nice with pedals and the onboard dirt, while nice to have, is not a priority. I have been looking at the bogner shiva and the Rivera knucklehead is there anything else I should consider. Given that I live in New Zealand trying out amps can be challenging. Thanks in advance.
