Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.

DOD "Digitech" TSR-12

Audio Proz Inv #: 19997

Studio reverb/multi-effects processor, true stereo (well built), midi control, sampler, I/O attenuators, full bandwidth, 24 bit signal, 48 bit processing. Near perfect, low use condition. I was a Digitech dealer years ago. This unit is as new, used occasionally in my home synth studio. It has minor update to correct signal level into reverb DAC. It now can do +14dbm operation with 6db better noise floor. Most Digitech products of this era were IVL based designs, truly a remarkable reverb which bettered Lexicon for the money spent. It does some excellent multi effect, multi tape echo, flanging etc. with wide enough bandwidth, dynamics to be effective on my concert grand piano, etc. Most pros didn not give digitech enough credit. Very reliable machine.
