Electronica Venta-Flanger PE-11 [Электроника Venta-Flanger ПЭ-11], 1991, made in USSR

Link: cheesyguitars | effectsdatabase | reverb | upgrade: in/out power supply | sovietguitars [Owner's Manual]

A Russian flanger PE-11. We suggest this one was produced after 1990 since the labeling is in English. The units seems to be a successor of Elektronika FL-01 flanger made by the same factory in the early 80's.
One may wonder what "manual" control does. As far as we know, it brings a little LCD screen with instructions how to use the pedal and when you turn the knob, it scrolls the text. The absence of the footswitch is another trick - there's a little voice sensor you can see on the upper left part of the pedal, and when you scream "Flanger!!!" it turns the effect on and off. Unfortunately, the "manual" and voice control options were broken on this particular pedal, so we had to take our best guess.

Zoom GFX-707 Guitar Multi-Effects Pedal, 1999, made in Japan


An effect should enhance the players performance. That has always been the ZOOM vision. However, we have witnessed technological advances that are so complicated that they can actually deprive players of the pleasure of creating sound.In recent years, what appears to be a rebound from the over-reliance on digital technology, there has been a return to a more simplified approach to music creation. The stomp box offers simple operation however lacks variety. Most multi-effect processors are convenient but take hours to create sounds. Until now, no processor has combined the best of both worlds. Convenience and ease of operation is the focus of the new GFX-707.

Vox Satchurator Joe Satriani Distortion [serial #000448], 2008, made in Japan


Link: effectsdatabase | Owner's Manual

VOX is pleased to introduce the first pedal in an ongoing collaboration with guitar icon Joe Satriani.

Drawing on Joe Satriani’s knowledge accumulated from decades of groundbreaking performances, both live and in the studio, VOX unveils a breakthrough in guitar tone – The Satchurator™ distortion pedal. Designed to Satriani’s exact specifications. The Satchurator produces Satriani’s signature tone and adds new features and improvements never before combined in a distortion pedal.

After almost a year of painstaking experimentation and road testing, Satriani and the VOX R&D team discovered the secrets to capturing the ultimate distortion tone in a modern-day pedal. The Satchurator is capable of very high gain levels, but operates more quietly and musically than other modern distortion pedals.

It also preserves the tone and pick-attack of the guitarist plugging into it, regardless of style, from subtly distorted blues tones through classic rock and shred. The result is a professional-quality pedal that recaptures sought-after vintage and modern sounds in a powerful, versatile and extremely musical pedal design.

It is designed to add a subtle amount of overdrive to your sound, capable of recreating that much sought-after "breakover" tone associated with vintage tube amplifiers. The TS7 has the exclusive "Hot" switch, which provides an extra amount of saturation for the modern player.
