from harmony central:
The controls are pretty self-explanatory, but you need to spend some time fine-tuning to get that perfect sound.
Sound Quality: 8
I play a Strat and a Tele with Seymour Duncan pickups, with and without overdrive, into Fender tube amps. Pretty basic. I often use a Boss RV-5 at the end of the chain set for just a slight amount of reverb, which works well with the CE-5 Chorus.
There has been alot of discussion on this forum about the similarities/differences between the Boss CE-5 and the Boss CH-1. I didn't know which to buy, so I bought both used and did my own "shootout" for a couple of days. Here is what I found:
NOISE: Both pedals are as quiet as church mice.
RATE: At the minimum settting, both pedals have indiscernably slow rates. At max, however, the CH-1 runs at about 4 cycles per second, while the CE-5 runs at about 8 cycles per second. This higher rate is actually useful with the depth turned down low.
TONE CONTROL: The CH-1 has a single "EQ" knob which has a very subtle effect. The CE-5 has a dual pot "Filter" control for bass and treble, and has a much greater and more useful effect on the tone. Note that the CE-5 controls are tone "cut" controls, so "normal" is full CW (not mid-range).
DEPTH: With the Depth control full CW, CH-1 has a deeper and richer sound than the CE-5.
GENERAL SOUND QUALITY: The CH-1 has a slightly colder, more "modern" sound than the CE-5 which is a bit warmer and more organic. This difference is subtle, and may simply be differences in EQ.
OVERALL RATING: The CE-5 has more range in its "Filter" (EQ) and Rate controls, making it somewhat more versatile than the CH-1. The CE-5 also has a slightly "warmer" sound. However, the CH-1 chorus efffect itself is deeper than the CH-1. So it was a toss-up until...
MODS: I immediately found a schematic for the CE-5 to try to figure out how to improve the depth of the effect. After several hours of fiddling I found the magic bullet: Change C22 from 5pF to 22pF (or just solder a 22 pF across C22 on the back of the board). Increasing C22 increases the amount of delay through the bucket-brigade IC (analog delay). Increasing C22 to 22pF has a dramatic and wonderful effect on the depth of the chorus effect.
If you fell inspired, try 22pF or other values until you get the sound you want. Radio Shack sells a nice assortment of ceramic capacitors that includes useful values for this mod. (RS part number 272-809). Email me if you have questions.
END RESULT: With this C22 mod, I LOVE the CE-5! It has the great range and versatility in the tone and rate controls plus a great depth in the chorus effect. I am keeping the CE-5 and selling the CH-1.
RATING: Without mod: 8 With mod: 10
I believe CH-1 is cheaper than CE-5, as quoted by SweeLee recently. so i went ebay to bid. guess how much i pay for my CE-5? $59SGD incl shipping. 8/10condition. real steal, cos many US ebayers refuse to ship here.
