Hi Bass Friends! I recently received this very cool amp from a highly reputable TBer. I've used it on two gigs so far and I really like it, but I'd love the additional wattage provided by the T900 or preferably the T1000. The amp is in great condition and here are details from the EICH website:
The ultra-compact T-series amps stand out by their power, punch and drive. You will experience every nuance of your playing in a totally new and distinct way – completely unaltered but with lots of punch, just the way you like it. The well-balanced four-band tone control suits all musical styles with a perfect sound. The “TASTE” control allows you to emphasize the tonal characteristics of your instrument – everything between a wiry mid-boost, a bold slap and an ultra-fat Reggae or Motown sound.
Jacks for FX loop, Tuner Out, Line Out, Line In and a transformer balanced pre/post switchable DI Out with ground lift lets you connect the T-series to the outside world. T-series amps are ideal for travelling around the world thanks to their voltage switch that allows operation at 230 or 115 volts 50 – 60 Hz.
A great new feature for late night rehearsal is the aux-in jack, where you can connect devices such as your mobile phone, a tablet or other to jam along to your favorite tunes listening with your headphones. You don‘t even have to connect a cabinet. It‘s never been easier.
Thanks to the unique “magnet fix pins“ your T-500 is always safely connected to the amp fixing bar of your EICH cabinet. (The magnet fix pins are not available in the US)

I'm in Scranton, PA (home of "The Office") and my zip code is 18504. If you're able to come by and would like to give it a listen, let me know and we can connect.
The pictures shown are from the listing from which I bought the amp, and nothing has changed!
Feel free to share your thoughts, offer trades (+/-), or talk with me about our local pizza shops if you'd like.
I'm always weak in the knees for Warmoth necks, but I'll consider other offers with an open mind. 
An in-person transaction would be fantastic, but we can figure out shipping if distance makes connecting in person simply implausible! We can do cash, Paypal F&F, or even Venmo if we must.
We'll figure out those details together when we reach that point... 
P.S., I'm also selling a very nice passive Warmoth Precision Bass body in Seafoam green/blue with a Bartolini pickup.
As always, I wish you a wonderful day and night, filled with amazing bass tone!
