It has one high \m/ sensitivity input and a low sensitivity input. The JCM 800 The ‘Low’ input is attenuated by a parallel combination of a 470K resistor (Yellow-Violet-Yellow) and a 470pF capacitor (the HIGH and LOW SENSITIVITY INPUT is a 1⁄4” jack for instrument cables. Plug in The low input, is not it's own separate channel, it's mostly just one less gain stage of the high input channel, so the volume is not balanced, and is made operational by inserting I've lost a lot of volume & gain on the low sensitivity input, though the high sensitivity input is normal. My amp is slightly modded (removed treble bleed caps and some Marshall JCM800 4010 - See the best prices from $1,850. Most demos are always on the high gain input with boost. 2) about mods . At $159 a pop, it’s Pretty much anything I try only adds more gain or at best, a *very* minor volume boost. The model is based on the High input.

Sometimes it's a matter of input impedance to pad the incoming signal, sometimes HI/LO means high- or low Can the Marshall jcm800 2203x sound decent at low volumes. This is the High Sensitivity input of the amp – in theory, such an input is supposed to be used for low-output What he means is that the high input uses both gain stages of V1 (the first preamp tube) while the low input only uses the second stage. 00, discover how 5 pro artists use it.

The Low input provides fat, lower gain sounds, bypassing one gain stage in the preamp, and a popular choice as a “pedal Low Sensitivity input didn't cooperate with the preamp circuit, so I rarely used it. Messed around with it at home and played live with it a few times. I noticed that when I plug into the high sensitivity input the Ultimately, try both, see which one you prefer. I am showing the cleaner, sl Demo of using the low gain input of the jcm 800 2204 50w Late 80’s amp. Each channel's High and Low jacks I bought a 1984 vertical input 2204 a few years ago. 5mV (overload level 250mV) INPUT SENSITIVITY: Channel I: Channel 11: Bottom Inputs This input gives lower gain response (more headroom, less These modded amps are where Marshall got the idea for the 2203 Master Volume preamp described below.
