1970s Traynor YBA‑1A Bassmaster MKII – Vintage 90‑Watt Tube Head

Up for sale is a 1970s Traynor YBA‑1A Bassmaster MKII, a powerful and highly regarded Canadian‑built tube head known for its punchy cleans, roaring overdrive, and tank‑like construction. These amps have earned a reputation as sleeper classics—often compared to early Marshalls but with their own bold voice and massive headroom.

Condition:  

Cosmetically, this YBA‑1A is in good condition for its age. It shows some wear from regular use over the decades, but nothing unexpected for a vintage workhorse. A few cosmetic notes worth mentioning:

• A couple of the control knobs are chipped or missing their reflector caps
• One knob is broken and cannot be reattached with the set screw (the knob is included with the amp)

None of these issues affect functionality, and the amp still presents well overall.

Service & Functionality:  

The amp was recently fully gone through and serviced, receiving a clean bill of health. It’s 100% functional and ready for many more years of reliable use. This is exactly what you want from a vintage Traynor—big tone, solid build, and dependable performance.

If you’re looking for a vintage tube head with serious volume, classic tone, and recent maintenance, this YBA‑1A Bassmaster MKII is a fantastic choice. Ready for the stage, studio, or your next loud adventure.
