Silverface champ amp has the perfect size. I remember one of my old friend has one.
I hear very good things about the Vox Pathfinder 15R too.
I love the Princeton Reverb for what I played on it, but it's a bit too big.
All my case are hand made by me. Thick and heavy cases. That why I want something small for easy transport.
At this moment I consider:
- Vox AC4C1-BL (hard to get 4 me)
- Vox Pathfinder 15R
- ZT Lunchbox
- Silverface champ
* Allen amp are interesting, but hard to get 4 me.
