📖 Description

Restore your vintage bass rig or give your custom pedal the "SVT Growl" aesthetic!

This is a faithful 18mm replica of the control knobs found on the legendary Ampeg SVT Blackline series. Known for their rugged, industrial design, these knobs are a must-have for bassists and builders looking to capture that classic 70s look.

Why this design stands out:

• Authentic Texture: Carefully modeled side knurling that provides the exact tactile feel of the original vintage hardware.
• Low Profile (18mm): While the original SVT knobs are larger, this 18mm version is perfectly scaled for pedal enclosures (1590B/125B) and modern bass preamps without losing the "massive" look.
• Pro-Level Indicator: Featuring a deep-recessed indicator line for maximum visibility on stage.

🛠 Technical Specifications

• Diameter: 18mm.
• Shaft Compatibility: Designed for standard 6.35mm (1/4") potentiometer shafts.
• Mounting System: Integrated Set-Screw design for a secure, professional fit.
• Hardware Needed: 1x M3 Nut + 1x M3 Set Screw (4mm or 5mm).

🔧 Assembly Instructions

1. Insert the Nut: Slide the M3 Nut into the internal hexagonal slot.
2. Prepare the Screw: Thread the M3 Set Screw into the hole until it meets the nut.
3. Mounting: Place the knob on your 6.35mm shaft and tighten the screw until it locks firmly.

🎨 Printing & Finishing Tips

• Resin (Best Result): Highly recommended for that smooth, injection-molded look.
• FDM (PLA/PETG): Use a 0.2mm nozzle and 0.1mm layer height.
• The "Pro" Look: Print in black and use white acrylic paint or a paint pen to fill the indicator line for high contrast.
• Color Choice: Don't feel limited to black! Print or paint in neon, transparent, or metallic filaments to make your gear stand out.
