A built-in distortion on Electric guitars that has been designed on the Simulation of Historical Drive Sounds.
In general, an external effector has been used the Distortion effect because of the fact that the external effector make more professional drive lately.
However, the QDD can make a precisely simulated sound with very simple and economical way of installation and provide a various distortion features that allows to increase your guitar's commercial value.
The way to install the QDD inside of guitar can eliminate the cable noise.
- Low profile / True bypass @ Clean tone / Heavy Metal distortion / Improved overdrive tone /
No switch popping noise / Long battery lifetime (3000 hours)
This is 4 step clean booster with passive bypass mode.
The QTB has 4 different level of gain control
- Low profile / True bypass @ Clean tone / 0dB / 6dB / 14dB / 20dB
No switch poping niose / Long battery lifetime (3000 hours)
QTA / QTP
This circuit was inspired by the historical 5 band tone selector used on Vintage guitars.
It has an Active and Passive version.
The QTA circuit has the gain control and provides 4 different peak resonances.
The low output impedance provides operation stability and low noise level.
The QTP has the passive tone filter of the traditional RC methods that makes 4 different tones while very little level is reduced.
EXP / EX3 Expand to Peak Controller EXP is the combined equalizer that has three unique functions in one unit. First is the frequency expander, second is a mid-band peak control and third is a flat booster. Another great feature of EXP / EX3 is unlikely conventional Bass / Middle / Treble Equalizer system that change over all gain while control the frequency character, the EXP / EX3 is designed to keep the over all gain constantly that provides operation stability while you are playing your guitar on the stage. Choose whether you want to have a full mid-range or accentuated high and low frequency for your excellent performance.
