Simble Predriver is not just a preamp, it is a preamp/booster/compressor/upper harmonic enhancer

 This musical tonal combination is totally adjustable with your picking attack and guitar volume pot. The amount of boost depends on the input signal level and HOT/COOL switch position. The maximum is about +10dB on lower level notes and average is about +6dB.

Simble Predriver’s special circuitry uses low noise transistor with high input impedance (over 2 Mohm) so you can boost even piezo pickups without tone loss. The output impedance is 50 Kohm so it works even in front of fuzz pedals. The power consumption is very small if you remove the input jack when not playing you can use the pedal with a 9V battery for few years!

Manual

Super Black

Like that legendary tone, this pedal produces intense drive while retaining high definition. The pedal also includes a built-in reverb circuit to add ambiance and depth to your sound.

“1”’s gain ranges from medium to very heavy distortion. The amount can be easily controlled via the volume control on your guitar. (Input impedance is set to facilitate this, and is somewhat negated if a buffer or buffered effect is used ahead of “1”.) The Brown knob controls the amount and harmonic overtones of the distortion. Getting the exact tonal quality is the key to this legendary sound and “1”’s Brown and Presence controls help it appropriately interface with a wide variety of pickups and amplifiers.

Hand-made in Finland premium quality tremolo pedal. Mad Professor Mellow Yellow Tremolo (MYT) is a true sine wave tremolo effect designed for tremolo tones from the of 50′s type soft swing to deep modulation with great playability, regardless of tremolo depth or speed.
The strength of the incoming signal is modulated by a sinusoidal oscillator, just like in the early amps, and modulation bias is set to give symmetrical modulation. This gives a very musical tremolo effect that blend very well with both clean and distorted guitar tones

Mellow Yellow Tremolo

Forest Green Compressor (FGC) is designed to meet the highest standards of guitar and bass compression.There is extremely low noise throughout the range and a high overload margin, which allows also a wide dynamic input range at minimum distortion and noise.
FGC is equipped with a special tone control to fine-tune the compressed sound for most transparent tone and effect. The pedal has a switchable compressor and sustainer mode. In Sustain mode, you can get a very dynamic, touch-sensitive tone with a long sustain. Here the attack is not lost, making the pedal suitable even for blues players and works great with slide playing.
