Ovaltone / HEAVY BLOW BASS-OVERDRIVE

メーカー製品ページ

Ovaltone's first bass-specific overdrive, ""HEAVY BLOW,"" offers a wide range of tones, from mild preamp-like saturation to powerful, fuzz-like drive that distorts the entire sound. The clean blend uses a ""PRE GAIN"" method that doesn't split the signal, achieving a superb sound that combines the original sound with the drive. The internal 30V boost drive delivers both thick lows and clear highs.

This is Ovaltone's first overdrive designed entirely for bass. Its versatile settings allow for a wide range of uses, from adding a subtle saturation like a preamp, to a natural drive sound blending in the original tone, to a deep, fuzz-like distortion.

The clean component isn't mixed by splitting the signal and then mixing it, but rather by using a pre-gain control to control the proportion of clean components in the main drive. This minimizes separation between clean and drive, resulting in a more unified sound.

The power supply is internally boosted to 30V, supporting a smooth bottom end and a thick, rich high-fret sound. We incorporated professional musicians' input during development, focusing on practicality in both the sound and the controls.

Note: Because this unit operates on an internally boosted 30V power supply, batteries (including external battery snaps) cannot be used. Furthermore, battery operation is not recommended, as the original sound will not be achieved.

The three large knobs are considered the main controls. GAIN: Controls the amount of distortion.
VOLUME: Controls the volume.
TONE: Controls the amount of high frequencies.

The small PRE GAIN knob in the center and the two push-push switches on the top of the unit are considered sub-controls.
All of these sub-controls relate to the pre-gain section (the first part of the circuit).

PRE GAIN: Controls the gain before the signal enters the main drive circuit.
Raising this control increases the clean components and overall distortion. If you want to increase only the proportion of clean components, raise PRE GAIN. If you don't need the increased distortion, lower GAIN to reduce it.

CLIP: Activates the clipper in the PRE GAIN section, allowing you to add distortion even in the PRE GAIN section.
CLIP on: Turning up the PRE GAIN knob mainly increases distortion.
This produces a squashed texture, making it recommended for achieving a fuzz sound. If the PRE GAIN is low, the CLIP threshold may not be reached, resulting in little change.

DEEP: Boosts the low frequencies of the signal amplified in the PRE GAIN section.
This is useful for creating sounds when you feel a lack of low frequencies by distorting the signal or when using the pedal as a preamp. When the PRE GAIN is raised, the relative amount of change becomes smaller.

We recommend starting with the following settings as a baseline for sound creation.

1. Set both push switches (CLIP and DEEP) to NORMAL (unpressed).

2. Set PRE GAIN to 12 o'clock (center).
In this state, you can create the basic sound of a typical overdrive pedal using the three knobs: GAIN, VOLUME, and TONE.
Once the basic sound is established, it's easier to understand the role of each control by thinking of it as fine-tuning the tone by manipulating the PRE GAIN knob and the two push switches (CLIP/DEEP).
