EBS TD660 incl. Case (ultra-mint!!) £743 Germany

[3Gorillas]

I’m selling an EBS TD660, one of my all-time favorite bass amps. It’s extremely versatile, powerful, dynamic, and built like a tank.
This unit was my backup — I used to own two — and since I’ve switched to its successor, this one can go.

 

The amp has very low playing hours and has been stored in a high-quality case from day one. I removed it from the case only for the photos: the condition is ultra-mint, without even the usual rack marks or scratches.

Prefer local pickup, but shipping is possible, of course (at buyer's cost and risk).

 

Price: GBP 743 / 850 Euro

Product Details

The EBS TD660 is a highly flexible, powerful bass amplifier that blends tube, Mosfet, and solid-state technology. It delivers a very neutral and transparent tone, preserving the natural character of your instrument.

It features a built-in compressor — the basis of the famous EBS MultiComp pedal — as well as a drive module with booster, capable of everything from warm overdrive to aggressive fuzz, always maintaining musicality.
The drive module can also run directly through the preamp tube, creating warm, tube-style saturation.

The intelligent 4-band EQ allows precise tone shaping. A notch filter removes unwanted frequencies (great for avoiding feedback), and the Character switch provides an instant mid-scoop.

Additional features include a DI output with optional speaker simulation, tuner out, and an effects loop — making this amp an excellent choice for touring bassists or anyone needing reliability and tonal flexibility.

This is not intended to be one of those passive-aggressive posts aimed at taking down a perfectly good sale, but I am genuinely perplexed as to why a head with a one-valve preamp comes in at nearly two stone in weight.  Is it just because it's built like a tank for the long haul?  Or am I missing something obvious?  (Probably the latter, but this is a genuine request.)

 

Whatever the answer, good luck with your sale.

Because it's a class A/B amp with a big heavy transformer not a class D ? The preamp tube is irrelevant - it's all in that power amp. Compared to EBS class D amps it'll have a sweeter more complex tone.

The 'proper' power amp with transformer adds a fair bit of weight along with the larger case size. And yes, they are built pretty tough too. It's a pretty typical weight for a non class D amp.
