A DesignsKGB-Itf Instrument Preamplifier
Independent shopping perspective
The Korena take
A Designs’ KGB-Itf is a single-channel solid-state preamp for high-impedance, unbalanced signals from guitar, bass guitar, and electronic keyboards. It combines high-voltage discrete op-amps with Cinemag balanced output transformers, and provides balanced XLR outputs alongside 1/4-inch instrument inputs. High, mid, and bass controls give the user three tone-control points, while low and high gain settings provide 35dB and 60dB respectively under the stated test conditions.
Strong match
Who this is for
- Studio routing of guitar, bass guitar, or electronic keyboards with high-impedance unbalanced signals.
- Single-channel instrument setups needing high, mid, and bass tone controls.
- Signal paths requiring balanced XLR output from the preamplifier.
Consider the trade-offs
When to look elsewhere
- Multi-channel instrument preamp setups, as the KGB-Itf is a single-channel unit.
