The harmonically rich sound and legendary performance of AMPEG products are redefined in the SVTDI. This Vacuum Tube Direct Injection device delivers unsurpassed quality, reliability and tonal flexibility in a compact, rock-solid package with exceptionally high cosmetic appeal. The SVTDI is easy to operate and is well suited for live performances or for use in the recording studio. Acoustic and electric
instruments will benefit from use of the SVTDI.
The SVTDI Vacuum Tube Direct Injection can take an unbalanced line level signal (bass, guitar, keyboard, etc.) and convert it into a balanced signal which can be sent through a long snake to that mixing board so far from the stage - without degradation of the signal! The
SVTDI offers direct or tube-buffered 1/4” and XLR output connections,
and has a switchable 6dB input attenuator to handle “hot” signals.

SCR-DI

In the world of effects there are some stompboxes that have become the stuff of myth and legend - some purely for their sound, others for their rarity value.
The Ampeg Scrambler is one of a small set that has become legendary on both counts.
It has a unique and sought after upper octave fuzz sound, but you'd have more chance of finding Elvis stacking shelves in your local Tesco than finding one second-hand market.
It sounds like the perfect excuse for a reissue, then. Which is just what Ampeg has done.

SCP-OD "Scrambler"

Liquifier

The Scrambler Series Pedals are based on the cosmetic design of the original Ampeg Scrambler pedals from 1969. Our SCP-OCT Bass Octave Pedal features the Octave Divider circuit used on the popular SVT-5PRO, duplicating the input signal one octave lower. This circuit tracks fast and holds the note, even at low volumes. The SCP-OCT is a great addition to your tone arsenal.
