Thank you both! I will check out the Gallery. An amp is not a must, I just had no idea if there usually are used amps in stores or if everybody sells those online nowadays.
I hope it is okay to jump in here with a question. I will be in London this weekend and I need a gig bag and a good (neoprene) strap. Can you recommend a store that has a good selection of accessories?
Also: are there stores that sell used amplifiers?
