Control Knobs

Benefits of correctly matched hardware

Solid or split shaft

Different diameters and spline patterns require matching knobs. Set-screw and push-fit types are not automatically interchangeable. Excessive force can damage the shaft or control; verify fit first.

Clearance and switching travel

The lower edge must clear the panel. Pull-operated controls need travel and grip. Check scale visibility and adjacent controls; an oversized decorative knob can hinder operation.

Material, finish and body contact

Plastic, metal and layered materials differ in thickness, stiffness and edge treatment. Parts should bear on intended surfaces without burrs or concentrated pressure. Screen colour does not guarantee a finish match. Agree installation, cleaning and removal methods for delicate finishes.

Check without forcing the fit

Before final assembly, check holes, moving parts and clearances. Controls should move freely and plates should seat evenly. Do not stretch plastic with screws or disguise mismatch with improvised packing. Any required modification should be assessed before altering original parts.

Key selection specifications

Exact model and production version

Record the instrument model, year or series and known modifications. Production variants can use different mounting standards. Photographs above and below the original part help but do not replace measurements. Modified instruments require checking the actual construction. Record dimensions in millimetres with clear measurement points.

Metric and imperial standards

Similar thread diameters may have different pitches, and shafts may use different splines. A part beginning to engage does not prove compatibility. Check drawings, markings and purpose. Manufacturer adapters must suit the intended application; improvised adapters can alter geometry or reliability.

Contents and total fitting cost

A package may hold one part, a pair or a full set. Check screws, nuts, washers, bushings, springs and accessories separately; a demonstration photograph does not establish inclusion. Agree fitting and setup work separately. Compare complete requirements to avoid missing small parts and delaying repair.

Care and preservation

Inspect retention, bearing surfaces and corrosion after installation. Use products compatible with hardware and instrument finishes; do not apply lubricant indiscriminately. Retain documentation and original parts when reversibility matters. Play, cracking or binding calls for inspection rather than increased tightening force.

Compatibility criteria

Before you buy

1. Confirm model, series and previous modifications.
2. Measure fit and compare all mountings with the drawing.
3. Check clearance, material, function and additional parts.
4. Agree fitting and setup work before buying.
5. Confirm availability, discount, warranty and delivery.

International brands: reference guide

Reference names of international guitar-parts brands and workshop suppliers. This is neither an exhaustive worldwide list nor current SoundsGood inventory. Not every brand offers a suitable part for every instrument. Check the individual series, dimensions, contents and availability separately.

Tenders, Prozorro and corporate procurement

For music schools, cultural institutions, studios and workshops, we prepare offers from instrument lists and technical requirements. Specify part type, mounting dimensions, material, quantity and contents. Prozorro and corporate orders follow the buyer’s documentation. Timing, price, warranty and supply scope are agreed separately. Fitting and setup are included only by explicit agreement.
