Free your Tone
COPPERSTONE interchangeable 3 Band Bass Guitar Preamp frees your instrument from being attached to one tone. Now, if your tone needs to change, you can replace your COPPERSTONE at will.
COPPERSTONE can be configured with 3 different mid frequency variations:
- single fixed frequency eg.: 250Hz
- two switchable frequencies eg.: 250Hz/400Hz using 2 way toggle switch
- tree switchable frequencies eg.: 250Hz/400Hz/1000Hz using 3 way toggle switch
More over, besides the standard frequencies available for COPPERSTONE, upon your order you can configure
your custom COPPERSTONE preamp with different frequencies to suits your needs.
Up to 3 Different switchable medium frequencies
In its basic setup, COPPERSTONE is adjusted as a unity gain device, where the input signal remains
the same as the output signal.
This means that the active and passive signals will remain the same
when the EQ is set flat on all the three bands. However, it is possible to boost the gain of COPPERSTONE
up to +9dB if necessary, especially if the signal of the pickup is not enough to drive the first stage of amplification.
Adjustable Gain
Flame, an optional module for COPPERSTONE, is a discrete electronic device. This subminiature module
monitors your battery status and will flash when the battery drops its voltage below the desired level.
Flame is installed as standard on all new JERZY DROZD creations except on PRELUDE instruments.

FLAME
For active or passive pickups
COPPERSTONE interchangeable 3 band bass guitar preamp can be installed on any bass guitar equipped with active or passive pickups.
COPPERSTONE operates on current as low as 0,84mA, which represents almost half of current consumed by other commercially available bass guitar preamps. The minimum voltage necessary to power COPPERSTONE is 3.8V, very low compared to the minimum of 5v or even 7v for other similar devices.
While a battery with a voltage of 5V would be considered "dead" for other preamps, COPPERSTONE is capable to squeeze it down to 3.8 volts with an impressive 70% performance. These factors, among others, make this unique bass preamp to stand out in terms of energy efficiency, which translates in less battery consumption, less vaste and, lastly in a lower operational cost.
