Because most people inquiring about a Mesa Boogie would have a reasonable idea of market value and how much they would want to spend, I decided to just ask for offers. The guide price is £1200.
Regarding photos, I have two which I tried to upload, but the upload data size limit is 97.7kb per jpg-type photo. Each photo was about 1.6MB. After lots of resizing and cropping, I ended up with two images that were of pretty poor quality and thought that they would not do justice to the amp.
You're welcome to email me and I'll send them by return email. Alternatively, I could upload the much-reduced-in-quality images and hope for the best.
