"The extras/mods are:
- 32 Banks of Memory (never run out of space for your acid lines!)
- Lithium Battery (No need for batteries to hold the memory. Should last 10yrs. Can still operate on batteries for portable use)
- Bright Green LEDS (my pics are a little yellow... but these LEDs are truly green. Awesome eerie color...)
- NEW tact switches with dust guard
- NEW top pots for synth control... and NEW Volume pot

- better CV & tuning
- mod for lower battery voltage use
- top 6 knobs are raised slightly for easier use, and less chance for paint rubbing off
- Larger values on C20 and C21 for better Bass response --- sounds great!
Absolutely a great acid synth... with no worry for loosing your programmed bass lines...
Small rubber feet on bottom can be removed, if desired... but they protect the 303 nicely.
Auction includes:
- TB-303 modded by the 303 man himself, Robin Whittle.
- Boss/Roland ACA 120 adapter (USA use)"
