If you want to sell this amp for more than a fire sale price:
1.post some photos, including the serial number. we want to know that it doesn't have a hot pink faceplate.
2. If you can't find your receipt in your email box, have Klaus send you another one so you can detail the upgrades.
3. asking for Paypal friends doesn't build trust. you can build paypal fee into your price.
When I see listings like this with little effort, I assume the packaging is going to also have little effort.
Sorry for your situation, I really hope you get the best price for your amp.
