CS-3 Compression Sustainer

43%of 70 owners recommend
43% recommend · 27% neutral · 30% don't
Owners praise
  • Delivers a hard, audible squash and long sustain that owners on both sides of the argument describe the same way, so what a buyer gets is not in dispute
  • Tightens up clean and palm-muted rhythm playing, with several owners saying those parts sit better in a band mix with it on
  • Cheap and durable enough to stay on a board for years, including one owner who has not taken it off in nine
Owners complain about
  • Noise climbs with the sustain control, and owners repeatedly report hiss once the knobs pass the middle of their travel, worse with drive or fuzz in the chain
  • Squeezes the life out of the signal for a good number of owners, who describe flattened picking dynamics rather than subtle control
  • Eats the low end on bass, the most repeated complaint from bass players, several of whom had to add the lows back or replace the pedal outright

Morning Glory V4

45%of 53 owners recommend
45% recommend · 34% neutral · 21% don't
Owners praise
  • Holds up as an always-on low-gain drive that owners leave on the board for years
  • Adds clarity and edge-of-breakup without covering up the amp's character
  • Stacks well in front of or behind other overdrives, fuzz and boosts
Owners complain about
  • Bright and treble-forward, and the higher gain side can turn shrill
  • Thins out the low end, which shows up most on bass and on already-lean rigs
  • Not the Marshall Bluesbreaker voice some buyers expect from the circuit

Which should you buy?

Get the CS-3 Compression Sustainer if
  • ✓Players who want compression they can hear working, with long sustain, rather than an invisible peak trimmer
  • ✓Anyone tightening up clean or palm-muted rhythm parts so they sit better in a band
  • ✓Budget boards where a tough, cheap pedal that stays put matters more than refinement
  • ✓Bass players who want more bite up top and do not mind adding the lows back with EQ
Skip it if
  • Bass players who need the low end intact, since eating it is the most repeated complaint from that group
  • Anyone after a transparent always-on compressor that controls peaks without coloring the tone
Get the Morning Glory V4 if
  • ✓Players who want one always-on low-gain drive that lives on the board
  • ✓Single coils into Fender-style clean amps, Strat into a Deluxe Reverb territory
  • ✓Boards where the overdrive has to stack with other dirt pedals or feed a fuzz
  • ✓Clean-to-breakup jangle and power pop, where a bit of extra sparkle helps
Skip it if
  • Anyone chasing a warm, dark, mid-heavy overdrive
  • Already-bright rigs, or humbuckers into a scooped amp where owners lose it in the mix

What CS-3 Compression Sustainer owners say

“The CS-3 is what I want my compressor pedal to sound like. You can get that real squashy sound it's what you're looking for. Mine did eventually fail though, that bummed me out.”
— MLoxxer on Reddit
“Great pedal - somehow less noisy than pricier compressors but not as squishy, although it does the clanky compression very well. Also great as a boost on lower compression levels.”
— procraffinator on Reddit
“I used a Cs3 on my board for like 6 months and really wanted to like it but to me it's a piece of junk for the same reasons you said. Noise everywhere if you surpass the middle of the knobs.”
— carlitox3 on Reddit

What Morning Glory V4 owners say

“Morning Glory is great as a low gain always on. I forced myself to take it off my board because it was keeping me from learning how to use my other boost/tone-shaping pedals lol.”
— Professional-Net6454 on Reddit
“I've got both and right now the MG is on the board. I love them both dearly, but the MG sounds a bit gnarlier to my ear, just a touch more breakup, which is what I want right now.”
— cromulentwrd on Reddit
“I find the MG too bright, so I end up using only a small fraction of the tone control’s range.”
