Killer
Since 1987
Founded in Japan in 1987 by guitar distributor George Azuma and Loudness guitar maestro Akira Takasaki, Killer Guitars is one of the most iconic high-performance shred guitar brands in heavy metal history. Built around Takasaki's uncompromising tonal demands, Killer revolutionized guitar construction with its patented Deep Insert Neck Joint—where the neck tenon extends deep into the body underneath the neck pickup cavity, uniting the endless sustain of neck-through construction with the explosive percussive snap of a bolt-on joint. From the flagship star-bodied KG-Prime to the versatile KG-Exploder, KG-Scary, and KG-Fascist, Killer instruments deliver thunderous low-end definition, blistering harmonic overtones, and peerless Japanese custom-shop engineering.

Killer Price Overview
Killer covers a wide range of instruments from entry-level to professional models. Typical used prices vary by condition, series and year. Higher-end USA models and limited editions retain value better than mass-market lines, while rare or vintage pieces often command significant premiums.
When evaluating value, consider originality (pickups, hardware), structural condition (neck, frets, finish) and documentation (serials, receipts, setup reports). Price dispersion across platforms is common; local stores offer service and inspection, whereas online marketplaces provide broader selection and price transparency.

Model-Specific Buying Guide
Each model has unique characteristics that affect both tone and value. Here's what to look for when buying specific models.
The Heavy Metal Holy Grail ($2,400 – $3,800 Used)
Patented Deep Insert Joint Verification
Remove the neck pickup to inspect the extended maple tongue running directly underneath the pickup cavity with anchor bolts—the hallmark of authentic MIJ Primes.
Original Floyd Rose Recessed Pocket
Check bridge routing depth and knife edges; genuine Primes feature deep back routes allowing extreme 3-semitone pitch raises without binding.
Body Horn Tip Inspection
The radical angular star tips on the lower and upper bouts are prone to minor dinging; evaluate paint chips against collector market value.
Pro Shredder Workhorse ($950 – $1,350 Used)
5-Bolt Semi-Deep Insert Stability
Features 4 bolts through the rear plate plus 1 hidden anchor under the neck pickup, providing 90% of the Prime's sustain at a fraction of the cost.
LQ-500 & LZ-510 Dyna-Bite Pickups
High-output ceramic and alnico pickups voiced specifically for singing leads and crushing rhythm articulation with zero high-gain mud.
Wheel Truss Rod Quick Adjustment
