I'm a pedal addict and liked plenty of the contributed posts in this thread. However...
That rehearsal room Ampeg micro amp is likely the issue. So get experimenting!
First try plugging your pedal board direct into the fx return in back BE CAREFUL turn last pedal volume really low as all amp controls might get bypassed.
This will test if it's the amp voicing that you don't like.
Next. Try plugging direct in (no pedals) but raising the amp up as high as you can, as far away from you that you can in the room. Dead guitar cabinets with castors are often floating around rehearsal spaces, or storage crates, that make raising amps easy.
This test will confirm if it's the amp positioning or not, eliminating the variable of the compressor.
The other test: get a DI and plug direct into the PA. Ask around for one to borrow, just not the cheapest (really cheap tend to lose lows).
This test will help confirm if it's the room or not.
Once you have answers to these, you'll be far more informed prior to your next pedal purchase. Otherwise you are at risk of getting a great pedal but it still sounding meh at rehearsal.
All the best with your journey
