Source Audio True Spring Settings Guide

The Source Audio True Spring is a dedicated spring reverb emulation pedal — modeling three distinct spring reverb tank types (small combo, large studio, and drip) with full control over dwell, tone, and mix. The True Spring is considered the most accurate spring reverb emulation available in pedal form, rivaling the actual spring tanks used in vintage Fender amps.

The best Source Audio True Spring settings start with: Dwell at 5/10, Tone at 5/10, Mix at 4/10, Type at 5/10. Adjust from there based on your amp, guitar, and room volume. For Blues: Dwell 5/10, Tone 5/10, Mix 5/10, Type 5/10.

What Each Control Does

Dwell
Short
Long
Reverb decay length — longer Dwell produces more spring reverb character and drip.
Tone
Dark
Bright
Frequency character of the spring reverb.
Mix
Dry
Wet
Spring reverb wet/dry blend.
Type
Small
Studio
Tank model — small combo, large combo, or large studio tank character.

Settings by Genre

Blues
Dwell5
Tone5
Mix5
Type5

Moderate Dwell, Type at large-combo — the True Spring for blues guitar reproduces the spring reverb character of a Fender Deluxe Reverb or Twin Reverb. Mix 5 keeps the reverb present but not overwhelming. This is the most common blues spring reverb application: audible reverb tail that adds dimension to clean and edge-of-breakup tones.

Country
Dwell4
Tone6
Mix4
Type3

Moderate Dwell, small tank — country amp spring reverb at practical settings. Small tank type produces the tighter, more present spring character of smaller combo amps. Tone 6 brightens the spring reverb to match the clean Telecaster character. Mix 4 keeps the reverb supporting without dominating.

Surf
Dwell8
Tone5
Mix7
Type7

High Dwell, high Mix — surf guitar spring reverb at full expression. Dwell 8 produces the long, dripping spring reverb characteristic of surf. Mix 7 pushes the reverb to a very wet level. The large studio tank type at this Dwell setting produces the distinctive spring "crash" when the guitar is struck hard.

Rock (moderate spring)
Dwell6
Tone5
Mix5
Type6

A larger tank type at moderate Dwell gives a fuller, more present spring character than the subtle blues setting, suited to rock rhythm and lead tones that want an obviously vintage-amp-style reverb.

Studio (dry-adjacent)
Dwell3
Tone5
Mix2
Type4

Short Dwell with low Mix keeps the reverb nearly invisible, adding a sense of space for recording without an obvious wet effect competing with other tracks in a mix.

Tips & Common Mistakes

  • The drip effect, the characteristic crashing and splashing sound when a spring tank is physically hit, occurs when Dwell is high and the signal suddenly stops — end a hard-picked chord abruptly to hear the characteristic spring drip. This is most pronounced with the large studio tank model at Dwell 7+.
  • Tank Type is a genuine tonal choice, not just a size label — the small combo tank sounds tighter and more present, while the large studio tank produces a longer, more diffuse character closer to a dedicated studio reverb unit.
  • This pedal is voiced specifically to emulate real spring hardware rather than a generic algorithmic reverb, which means it responds to picking dynamics and can produce the same physical drip and boing artifacts a real tank would.
  • For players switching from a real spring-reverb amp, matching Dwell and Mix to the amp own reverb settings by ear, rather than starting from the pedal defaults, gets a faster, more familiar starting point.
  • Pairing this pedal with a genuinely clean amp channel preserves the accuracy of the spring emulation — running it into an already-driven amp changes how the reverb tail interacts with the saturated signal in ways a real spring tank behind a clean amp would not replicate.
