These Ampeg full revalve kits are put together to provide a sonic upgrade to your Ampeg. I own and have played over the past 30 years Ampeg SVT, Original V4B and for recording used the B15-N portaflex.These amps are still the kings of bass amplifier in my opinion and these kits use the best of New Old Stock valves and modern day production items to give you the best sound out of these lengendary bass amps.

The Harma 7025 STR JJ upgrade kit is designed to give your SVT 2 Pro head a clean sound but when run with a fair amount of input gain will give a little valve distortion that will recreate the edge of the original valve vintage SVT.

The Harma 7025 STR DR250 is a high gain valve selected for bass amps and it will not distort as soon or sound as fizzy as the standard Chinese 12AX7C. The Harma 7025 therefore offers better performance with this regard. The valve is very well balanced with nice even bass which has plenty of depth with the top end being more aggressive and hard.

The Harma ECC82 STR follows the frame grid style of plate construction which makes it super low in microphonics. The sound is extremely well balanced and transparent. This valve also has less midrange emphasis than the Harma ECC822 Retro allowing you to dial in the amount of fatness that you want. It supplies a clear and deep bass response with a fast attack which makes it ideal for those percussive styles of playing

The valve when used in conjunction with the extensive tonal shaping of the SVT Classic head it can be used to get the full range of vintage punky Precision bass type clank to a more modern rounded bass sound with a harder edge.

The JJ 6550 provides very lively punchy performance with a silky smooth midrange.
The low end bass response is very tight with plenty of depth and detail. it is also superbly balanced with the mids sitting in the correct position and providing plenty of clear top end detail without being harsh

This set will suit the player who wants to get more of a vintage throaty ampeg valve sound
with plenty of punch with aggressive highs.

5 Specially selected Harma 7025 STR DR250
3 Specially selected Harma ECC82 STR
