If this amp was modded by FJA, wouldn't FJA add some sort of marks to it that clearly state it was modded by them?
I've never heard of anyone modding a Dual Recto into a Triple Recto and removing everything that makes it a Rectifier (like removing the tube rectifiers), so I wouldn't touch it. I'm pretty sure this is the same amp that pops up for sale at GC every few months, so if you really do intend to pick it up, at least they have a good return policy, even if their customer service is on par Indian telesales.
As for your posts, I don't think any of us have an issues with helping anyone make an informed decision based on our experiences. I always try to be as welcoming as I can. I only speak for myself, but seeing your VS threads...followed by a THIS IS THE BESTEST MAP EVAR MAYDED...followed by THIS MAP IS THE WORST MAP EVAR...is pretty annoying.
If an amp doesn't sound or feel the way you want it to, don't buy it. There's been plenty of guys that have got a range of great tones from Marks, Rectos and Peaveys...and when we read posts like what you've written about your Mark V, it just shows that you don't know how to use the tools you already have.
Just to be clear, I'm not trying to upset you, just trying to help you understand the way it comes across, and maybe shed some light as to why you may get negative feedback on threads you start. There used to be a forumite that went by "KSEFan" back in the good 'ole days, and every single thread that he posted in became a complete bloodbath...
