Lately I've been wanting to get something slightly more akin to a vintage Marshall sound, i.e. JTM-45. My current amp is a handwired Vox AC30 with a Celestion Alnico Blue and a G12H30. I don't want to sell or trade the amp because I really like it. So I've been looking into the Zvex Box of Rock as a pedal to run into the Vox to achieve something closer to JTM-45 tone. I won't be able to try one out before buying. Anyone ever used one of these with a Vox? I'm wondering if it'll do what I'm wanting. Voxes are sometimes picky about overdrives. I'm also open to other Marshall voiced pedals if anyone has any suggestions. Thanks.
