I’ve got a deal in the works for a Mesa mk v 90w head used off of a private seller. Can’t find a new one for nothing. Totally sold out. Mesa is having trouble getting parts especially the bigger transformers for 100 watters from what I hear. Even used these are a decent chunk of change at least for me. Being a private seller I’m taking a chance with any issues. Ie: no return policy. Plus my tech quit doing repairs to focus on building pedals and custom work. Question is do I jump on this or wait for a store with a return policy. I’ve missed out on at least 3 from guitar center used. The last one pissed me off because it was cheaper and I went through through the whole ordering process only to be told at the end that it had already been sold.
