GVA_T5_B5_SM57_C_100.
The first time you see it, it may feel like code. But it's a "map" — the recording conditions laid out as they are. Once you can read it, you know what a profile contains before you buy.
It isn't hard. Just take the tokens one at a time.
The name is the recording conditions, laid out in order
A CSL profile name is not decoration.
Which amp, at what setting, through which mic, at what position it was recorded — in that order. We don't hoist the amp's name in big letters while hiding the contents. Everything you need is inside the name.
Breaking down the tokens
Read GVA_T5_B5_SM57_C_100 segment by segment:
GVA… the amp model (Greco GVA CUSTOM)T5_B5… the amp setting. Treble at 5, Bass at 5SM57… the mic used (the classic dynamic)C… the mic position. C is Center, E is Edge100… the mic ratio. 100 is a single mic. For a blend, a mix ratio like60_40appears
So GVA_T7_B4_SM57_GT67_E_60_40 reads as "Treble 7, Bass 4 / a blend of SM57 and GT-67 (60 to 40) / Edge." From the name alone you can guess whether it's brighter or thicker, forward or settled.
Reading names makes choosing fast
Once you can read them, you can narrow dozens of takes just by looking — before you audition anything.
Want a tight, forward sound? Look for SM57 and C (Center). Want thick and round? GT67. Want something calmer, less fatiguing? E (Edge). Brighter day? A larger T (Treble) number. Thick and dark? A small T and a big B (Bass). Want blend thickness? A take with a ratio like 60_40. You only need to audition the few you've flagged. However many dozens there are, you can sieve them at the name stage, so you never get lost.
Work backward from a goal. "A tight backing tone for home recording that won't clash with the other parts" → a mid-focused SM57_C setting. "A thicker lead that sits forward" → a GT67 blend. "A stream-friendly, non-fatiguing tone" → a settled E take. Once the goal is set, the tokens to search for are set. This is only possible because the conditions are in the name. With an ordinary profile that lists only the amp name, it doesn't work.
Why put the conditions in the name
What CSL sells is not "the best tone" but the record of a sound that actually existed.
If it's a record, hiding the conditions is meaningless — the conditions it was recorded under are the substance of the record. So the name is built to reveal the setting, mic, position, and ratio in full. We don't sell by hoisting the amp name and making the contents a black box. Before you buy, the contents are visible; after you buy, you can return to the same conditions anytime. The name is the map for that.
The string that looks like code is, in fact, an expression of a "we don't hide it" stance. Where many profiles get names like Amazing Lead Tone 01 that say nothing about the contents, CSL deliberately chooses a blunt but honest name like GVA_T5_B5_SM57_C_100. Legibility over coolness. Even the naming carries CSL's position: don't hide the record.
Start with the free sample and match the names against the sounds. The reading gets into your body fast.
In short
A CSL profile name is not code — it's a map of conditions. Amp, setting, mic, position, ratio, in that order.
Once you can read it, you know the contents before buying, and choosing gets fast. Keeping the conditions in the name is CSL's "don't hide the record" policy itself.
