Pretty rare these come up.
Like they say -
"At 4.3 lbʼs (less than 2 Kg) the WTX500 is the true original lightweight bass amplifier. Not only is this little amp easy to transport, but with a maximum power output of 500W at 4Ω, this amplifier is more than capable of holding its own in a live band situation."
"Featuring 3 stage EQ, Bass Boost, Mid Shift, "Enhance", ¼" headphone output, footswitch input and left and right ¼" auxiliary input and Mute switch. The WTX500 has the power to deliver, at home, on the stage and in the studio."
Excellent condion, hardly used in ace bag - price includes UK postage.
