Hello, noticed that you offered a Digiverb in response to an offer, just wondered if it was in response to the offer of the Telefunken tube in the trade or partial cash? Id be interested in the pedal if its older-tested/NOS 12AX7s you might be interested in...all tested for most important preamp tube parameters in three diff calibrated testers and I test for the most important thing a lot of tube guys dont bother to test..microphonics/noise. All are run for min of 1 hour in a low gain and high gain amp head at full voltages. Also have older-tested/NOS power tubes. Let me know if interested. THX, bestfoot4ward, back to the board for the first time since last month after emergency surgury....
