Goldo Guitar Pre Amp Booster +15db

Compact preamplifier for electric guitar by Göldo

This compact preamp is designed to fit inside the instrument. An internal trim pot allows for individually adjustable volume gain of up to +15 dB. The preamp operates completely linearly and does not alter the pickup signal at all.

It offers a low-impedance, buffered output that perfectly matches the input impedance of amplifiers, recording interfaces, or PA systems. Plus, the input of tube amplifiers is driven more strongly, causing the tube stages to saturate earlier, resulting in a warmly distorted sound.

Additionally, the guitar's volume potentiometer offers greater control over nuances without losing the instrument's high end. Thanks to its low-impedance output, long cables and multiple effects pedal chains can also be used without losing high end, dynamics, or clarity.

It works with both passive and active pickups and is powered by a 9-volt battery. The stereo jack and battery clip come pre-installed on the module.

⚠️ Caution: If the preamp is not installed with a switch, it always remains active when the jack is plugged in.

For more practical and functional use, it is recommended to mount a power switch, such as a CTS Premium Push-Pull potentiometer, which is placed in the volume pot position.

Pulling the pot out activates the preamp (active mode). Pushing it in deactivates it (passive mode).

This system allows you to use the preamp only when desired (for example, during solos), and if the 9V battery runs out, you can continue to use the guitar passively and normally.

Without this switch, if the battery runs out, the guitar loses all volume and cannot be used.

Facility:

The complete system (module, jack, battery, cables, trim pot) fits perfectly into the electronics slots of Telecaster, Stratocaster and similar guitars.

Assembly and sealing:

If the option with all components soldered is purchased, the package will be opened to make the connections.

The products are new, but are delivered unsealed after assembly in the workshop.
