I bought my Traynor SB500H (& SB200H) in New York. It replaced a Little Mark head. If you haven't heard this little Traynor head (or the smaller SB200H) try to get to audition one. (If, like me, you're in the UK, you'll have to skip auditioning and take my word for it! It's virtually impossible to buy Traynor amps in the UK) This is a little box of amazingly warm, clear, rich tone. I've had both my Traynor heads for 18+ months and I am never, ever disappointed. They're simple, functional, no gimmicks or frills, and they've got a monstrously lovely sound. I sold my Ashdown & Markbass heads, they were just surplus to requirements. I still use my EBS preamp for recording, but also my Traynors too. I've become such a fan-girl but virtually no one in the UK has even heard of Traynor Amps, yet they've been around since 1963. I could rave-on about these little lightweight heads but they do have to be heard to be believed! I poopie you not! A total WINNER by Traynor. Such a shame they have no distribution in the UK - British bassists are losing out.
