Operating Instructions OVERVIEW: Congratulations on your choice of the DUAL RECTIFIER TREM-O-VERB. You have purchased a handbuilt instrument of the finest quality and craftsmanship. A unique blend of yesteryears’ black magic power section design combined with our race-shop approach to finely tuned, high gain pre-amp circuitry leaves the TREM-O-VERB standing alone...instantly a classic destined for vintage status. - Page 6 FRONT PANEL: First familiarize yourself with the layout of the front panel and locate the Footswitch Input jack. This jack, when connected to your footswitch will allow you to select either the Lead or Rhythm channel remotely. The rear panel Channel Select toggle must be in the UP position (ORANGE.) If you don’t have a footswitch available, the Channel Switch located on the rear panel ( far left end of panel if facing front of amp ) will activate this switching procedure.
- Page 7 GAIN: Like most amplifiers, the GAIN Control in each channel determines it’s sensitivity and overall tonal characteristics. It meters the amount of Gain (volume) that your guitar signal will produce. In the T-VERB, we paid special attention to the amount and frequencies of Gain present in each mode, making sure the whole range of available Gain is musically usable.
- Page 8 PRESENCE: These are controls that work in the power section to reduce attack and brightness. They work on a different frequency than the TREBLE Control, and depending on the mode chosen, and the amount of Gain dialed up, can sound higher or lower than the Treble frequency.
- Page 9 MASTER: A simple control found on most amps today, these serve to balance the playing level of the two channels. They enable the pre-amps Gain Control to be used in a wide range of settings, while never having to affect the listening level. On the T-VERB these MASTERS serve another purpose as well.

up this effect for over-use can be ineffective and can even dilute what might otherwise be a nice sounding tone. External switching of the TREMOLO is possible by a remote footswitch, see section on External Switching. To obtain the smoothest TREMOLO effect, bear in mind that for every range of speed - there is a sweet spot on the Intensity Control. -

RECTIFIER SELECT: This patented switchable feature allows you to select between two different types of rectifiers for different sounds and feel. It first appeared on our Dual Rectifier Solo Head and is, in fact, part of the magic behind the whole Dual Rectifier series of amplifiers. -

Certainly no cause for alarm, this quirky behavior comes with the territory and the Tone. Much like changing a light bulb, you don’t need a technician to cure these types of minor user serviceable annoyances and in fact, you’ll be amazed at how easy it is to cure tube problems...by simply swapping out a pre-amp or power tube! First may we suggest that you set the amplifier up on something so that you can get to the tubes comfortably without having to bend...

Just note the color designation on the tube label so that we can send you the appropriate match. DIAGNOSING PRE-AMP TUBE PROBLEMS: Because your amplifier is an all tube design, it is quite possible that at some point you will experience minors pre-amp tube noise.

- Page 21 Voltage and current are NOT the same. Current is the AMOUNT of electricity, the “quantity” — and is measured in amperes. Voltage is the degree of electric charge — like the “pressure” to use the old water analogy. Let me illustrate how different voltage and current are: When you scrape your feet across a carpetted floor in dry, wintery conditions, your body can become charged with 50,000 to 100,000 volts of static electricity.
