Hi, I hope this doesn't sound unreasonable but my wife isn't keen on people she doesn't know coming to our house - I can swing it occasionally when I know the buyer or they have good feedback on BassChat. However, this is your first post so I'm afraid it won't fly.
What I can say - if it helps - is that the amp was played at the weekend by BCer @JamesFlashG who I am sure would happily vouch for it being in full working condition. Also, I have about 9 or 10 pages of uniformly positive feedback on BassChat, so I am a trustworthy seller.
As for age of the amp, I bought it off the forum six months ago so I don't honestly know. I have used it for several gigs and a number of rehearsals but mainly its been home use and so not pushed. You can see from the pics its in good (8 or even 9 out of 10) condition. I can send more pics also if needed.
