Wrocket Top Boost 30Watt - 4 x EL84 Head kit

Product code: 14-WRKT30-1

For those who are not familiar with Trainwreck amps they are well worth looking up, unfortunately thought they were produced in low quantities making their second hand value very high and that is if you can find one available for purchase, probably the closest thing to unobtanium in the modern world!  Thats where building your own amp can help bring you closer to the magic that these classic amps offer.

This kit is based on the Rocket amp, which is a 4 x EL84 Top boost single channel amp, that is itself a derivative of the amps used by British Rock and Roll bands in the 60s with a touch more gain.

Tone wise the amp has big clear chimey clean tones that work well for country and rock and roll and turning up the volume control quickly brings out super smooth overdrive that, with no negative feedback, can sustain for days and be easily controlled with the volume knob on your guitar or a volume foot pedal.

Use the drop down boxes above to select the parts you want in the kit, the price may change after specific selections are made. The default kit options offer great tone at an affordable price.

Important: If you do not buy the transformers with the kit the chassis will not be drilled for any transformers so you can arrange the layout to suite
