3.1SELECTING SOUNDS

When you’re ready to tweak the settings for both of the fundamental sounds that the EDITION TUBE has to offer, we recommend you proceed as follows:

•Dial in all your sound settings with the guitar’s volume knob turned all the way up so that it give the amp the highest possible level to work with.

•First concentrate on tuning the CLEAN channel VOLUME knob to dial in the desired volume level and amount of overdrive.

•Once you’re satisfied with that sound, activate the LEAD channel and use the GAIN knob to shape the second fundamental sound to suit your taste.

•Now adjust the LEAD MASTER to dial in the desired balance of levels between the LEAD and CLEAN channels.

3.2 USING SIGNAL PROCESSORS

The EDITION TUBE is equipped with a serial effects loop. This means that the entire preamp signal is routed to the FX device and processed there. For this reason, use only high- quality signal processors that do not color the signal unnecessarily, add undue noise, or impair its sound quality.

CONNECTING EFFECT DEVICES:

•Connect the SEND jack to the processor‘s input, and the RETURN jack to the processor‘s output.

•To avoid noise, signal loss, and signals from being cut off, use high-quality patch cords only.

•Make sure the processor is not distorting the signal. Check the processor's level meter and use its input and output controls to dial in a suitable level.

•Unless you’re going for bizarre lo-fi effects, distortion devices are not designed for use in an FX loop. As a rule of thumb, any kind of device that compresses the signal should be connected first in the signal chain. Depending on the type of effect you want to achieve, you may want to connect a compressor to the amp's input.

•If you are using several processors or stomp boxes, ensure you connect them in the proper sequence.

Volume pedals, wah-wahs and the like evoke a slightly different sound and elicit a different response when you plug them into the EDITION TUBE’s front panel input rather than the effects loop. Both can sound hip, so which option you choose is a matter of personal preference.

4.0 REPLACING TUBES, SERVICE AND PREVENTIVE MAINTENANCE

Your EDITION TUBE features factory-equipped EL84 and
12AX7A tubes. They are first burned in and then checked
for their electrical and mechanical properties (micropho-
nics), selected and matched, and then given a final audio
and response test once they have been installed in a
EDITION TUBE. One of the most important steps in the testing

process is power tube matching, i.e. selecting and pairing	ENGLISH
tubes with identical characteristics.	ENGLISH
WHEN SHOULD YOU REPLACE TUBES?
The tubes in your EDITION TUBE are of exceptionally high
quality and will last extremely long. If you do encounter a
quality and will last extremely long. If you do encounter a
problem, first check whether one of the following situations
apply:

•Is the defect a problem caused by a faulty or worn-out tube, or is there actually a peripheral problem, for instance a defective speaker cable that caused damage to the tube? If this is the case, unless you correct the defect first, the problem will recur once you have installed a new tube.

•Did the AC power supply fluctuate during operation? Whereas digital equipment often malfunctions when the power supply dips below a minimum value, all-tube amps tend to malfunction when the power level rises above a certain value. Generators and faulty high-power circuits often cause these power fluctuations.

•Did a fuse trip although there was no plausible cause? Aging fuses, particle ionization in the tube or spark-over due to power spikes may cause this type of problem. In this case, replacing a tube will not solve the problem.

•Old tubes begin to show signs of wear after they have been in operation for a very long time: increased micro- phonics and noise, treble loss, weak power output, muddy sound, etc. are all indicators of pending tube failure. Power amp tubes wear out faster than preamp tubes. If you encounter these problems, replace the tubes. Not only do old tubes sound bad, they also have a tendency to fail altogether.
