Legendary and Vintage
It was a sort of standard in the '70s and '80s. So, if you play classic Rock or also Blues it can be a perfect solution to recreate those atmospheres. It has been produced in many versions, always identified with an additional letter to the serial number: A, B and so on. Differences between these versions can be very important, depending on the used chips.
More simple is impossible
Only two controls. Let's see them.
It modifies the mix between the guitar signal and the Overdrive. Obviously, turning it clockwise increases the volume of the effect. An interesting characteristic of the OD-1 is the transparence, always an important added value for a pedal. It doesn't color the original tone, and the bypass is much efficient.
Simply, it adds more distortion. The OD-1 is particularly sensitive to the pression, or if we want to the force, on the strings. This particularity is a great opportunity for an expert guitarist, since it allows a remarkable expressivity, but also a great difficulty, if your technique is still at the beginning. Another important characteristic is that this pedal creates an Overdrive similar to that of a tube amp. It works. The sound is full and warm. Certainly, much pleasant. As a whole, the final result is very good. It cannot disappoint.
Like i said at the beginning of this review, it has been produced in many versions that can be very different among them, according to the used chip. Generally, it is rather clean and it tends to cut lows. For someone this can be annoying, but you can use the tone control on the guitar, or on the amp, to better the situation. Anyhow, the character of the OD-1 is that typical of the '70s, and it is very far from the digital of the modern devices. It can be slightly noisy, but satisfactions are guaranteed. With regard to the price it can vary very much. It depends on the general conditions, if used. My personal opinion is that this is a great value product. It makes really a good job, and can be useful in many different situations.
