In 9-volt setting the Pro+ sounds and functions like the standard OD-9 with the added option of a healthy +3 dB of midrange boost at approximately 800 Hz (actual frequency is dependent on Control settings) – great for cutting through a band during solos. Either as boost. we put the zero gain and the volume loud enough. It colors the sound and gives a bit of overdrive on the agreements, it is superb. The sound quality is fantastic, although the pedals respcte the sound of the guitar and the ampli.Je used with a Start to find the sounds of SRV, if not with a 335 to "scream "The PAF or with a telecaster riffs to make way Keith Richards.Bref this is not one like the other pedals, that is THE essential pedals. The OD-9 is a true-to-spec reissue of the legendary 1980’s OD-9/TS-9 circuit, with the addition of true bypass switching for clean, uncolored tone when bypassed. I put a good quality score sheets and good response from the pedal to most power supplies (rather than 9V ...)

Even the pedal Ibanez TS9 to. Maxon IBANEZ manufactured the pedal and finally decided to leave under its own brand. In addition it is cheaper! hehe! Coupled with a Proco Rat 2 for a combo / overdrive-distortion, it's just magical, harmonious and "get into it". LED Power/Battery Life Indicator - Ultra bright LED indicates effect status (on/off). Dim or no LED indicates that the battery is low or not installed. Can be used on a clean channel as a channel saturated or even ahead of another distortion pedal to give you a potato with the fire of God!Like the OD808, the OD-9 provides the natural, mild overdrive of a tube amp without sacrificing the guitar's original tone. It can also be used as a clean booster to provide increased gain from an amplifier.

Looking at the OD-9’s circuit, you’ll realize that this is not some redesign being cleverly marketed as a reissue – this is THE original OD-9 (TS-9) circuit, yet with the addition of true bypass switching. Even the PC board is the same one that Maxon’s been using for the past 30+ years, complete with empty slots where parts for the FET switching circuit have been left out! The Maxon OD9 includes an exact replica of the printed circuit TS9 of the time but it also includes a Tru Bypass, which explains the absence of certain components because their functions are managed by the DPDT switch (it is good tps is a bit interested in electronics before distort the notice of beliefs). Like the original, the current production OD-9 features the NJM (JRC) 4558D Op Amp – an essential component for authentic “TS” tone. The OD-9 Pro Plus's new circuit uses different output resistors than its predecessor. After the unit's initial release it was discovered to have a high susceptibility to noise due to static electricity buildup. To improve performance, the values of the output resistors on the OD-9 were increased, but their positions kept the same as the original. This circuit change has no audible affect on the sound of the unit, save for reducing unwanted noise levels. In addition, the OD-9 features True Bypass Switching for natural, uncompromised tone in bypass. The NJM is smoother sounding and less compressed than other Op Amps, offering superior sound quality with low noise.Like the original, the current production OD-9 features the NJM (JRC) 4558D Op Amp – an essential component for authentic “TS” tone.

AC/DC Power Operation - Power using 9-volt battery (supplied) or AC adapter (Maxon AC210N optional).

Its hard to explain exactly why..but there is a singing musical quality in the tone which I don't remember my Ibanez TS-9 in the '90's having to just the same extent!.....its a very natural pedal to play..and thats one thing about it,you can really play it,not just stomp on it and it seems to work with you and co-operate with your intentions....I'm fortunate to have acquired some nice old guitars over the years and whether its with PAF,original Fender Wide Range,P90's,Fender Tele and Strat single coils it always seems to bring out the best...I've yet to find a guitar or amp it won't work beautifully with... I 've never had overdrive pedals, 30 years since I played guitar I always prfr the distortion of a Mesa or the crunch of a Marschal, but reading this force and this about the legendary Tube Screamer, I inquired and presto! adopted!While the Maxon OD-9 is true bypass, the input and output buffers are retained. So it has a vintage-correct circuit, but the buffers are only in the signal path when the pedal is switched on.
