The Plex

The echoplex is back, Rock Hard Inc. re-issues original echoplex design as ThePLEX!

the processor Formally known as EchoPlex! There are few musical experiences as satisfying as plugging an EchoPlex between a guitar and an amp.From snappy slapback echos to cascading flurries of notes to riffs that bounce off each other in perfect rhythm,the effects created by an EchoPlex pro- vide infinite creative possibilities. Rock Hard,Inc.has started manu- facturing an amazing y accurate re- production of EP-2 EchoPlex called "The Plex".Housed in a Tolex-covered box with a snap-shut latch and a car- rying handle,just like the original. The Plex has a familiar,retro-style ap- pearance,but thanks to the use of modern materials and components, the unit weighs considerably less than the original version.But the lighter weight is about the only dif- ference between The Plex and the original EP-2.Every aspect of the EP- 2's tone was analyzed in detail,and a circuit was developed that dupli- cates this tone with all of the warmth, fullness and character intact. Playing through The Plex is like go- ing back in time.After getting used to the ultra-clean charac- teristics of digital delays, it is easy to forget what a real echo unit is supposed to sound like,and if you've never experienced this before you are in for a real treat.The more you play with The Plex,the more it feels like you are controlling another instru- ment instead of playing an effect that is controlling you. ECHO DELAY CONTROL - This control allows you to adjust length of echo delay in an infinite number of increments.This means you can set your own tempo instead of having to play with a pre-set tempo.On the top of the cover plate you will see a numbered scale.This represents no set units.It is only a log scale to reference where the tempo and echo delay is located on a particular song. ECHO OFF - Allows you to turn the echo on and off via a foot pedal. BALANCE CONTROL - The balance control allows you to adjust from dry to only echo,and anywhere in between. REPEAT CONTROL - This allows you to adjust the number of repeats per echo. RECORD LEVEL ADJUSTMENT - Record knob increases the amount of tape saturation.It will increase the intensity of echo as the tape becomes more saturated.Over saturation of tape will increase distortion level. OUTPUT - To amp. INPUT - Pull slide bar to the right.This engages the pinch roller for recording and provides a 1/4" jack for guitar. PLAYBACK FEATURE - This feature enables you to record a two minute loop that you can then play an accompaniment to.This is not sound on sound as in the EP 5,and takes a great deal of experience and accuracy to accomplish. This can be done by engaging the foot switch.   SPECIFICATIONS Model: TP 100 Power requirements: 100V AC,50/60 Hz,30W 120V AC,60 Hz,30W 230V AC,50 Hz,30W 240V AC,50 Hz,30W Input impedance: 200 k * Preamp output impedance: Adjustable from 600 * to 1k * Power amp in sensitivity: Typically 100 mV Tubes: 3 Sovtex 12 AX7A tubes Fuse: 1.6A fuse for 120V version .08A fuse for 230V and 240V versions Footswitch: 1 button footswitch,controls echo on and off (optional).
