These are the frequently asked questions we have put out for you. If they are unable to address your concerns, please write to us.

  • Q1: How does the Rosewood KILN works?
    The Rosewood KILN dehumidifies by warming your guitar gently. Three key principles of wood drying; (1) constant heat supply, (2) warm environment & (3) air circulation underpinned the ways it works. More reading can be found on page 8 of this document: Drying Hardwood Lumber
  • Q2: How to use it?

  • Q3: How long should I leave the Rosewood KILN in my guitar?
    Per dehumidification treatment is 8 hours. While you may cut short the duration, it isn't recommended to go way beyond 8 hours.
  • Q4: How frequent should I use the Rosewood KILN?
    There is no hard or fast rule on the frequency of use. If you suspect your guitar(s) has taken in excessive moisture, use it. As a guide, you could use it daily or weekly as you deem fit.
  • Q5: How do I know that my guitar has been dehumidified?
    Using a wood moist measuring meter is the most definitive way. However the manner is invasive to your guitar. It is not recommended thus it would be better to base on the playability of your guitar to gauge. The immediate area about the guitar bridge bulges when excessive moisture is in your guitar. That increases string action and diminishes playability. After the application of the Rosewood KILN, you should get better playability and that would mean your guitar is dehumidified.
  • Q6: Can I use the Rosewood KILN whilst my guitar is inside its guitar bag or hardcase?
    Having sustained air circulation is required for the KILN to dehumidify your guitar. Placing your price guitar inisde its bag or hardcase may hinder sustained air circulation. This can cause heat to build up within your guitar box. Unless air circulation is sustained, placing your guitar inside bag or hardcase may not be a good idea. See the proper use of the KILN while the guitar is inside its hardcase here:
  • Q7: Can I use the Rosewood KILN whilst my guitar is placed on a stand or hung on a wall mount?
    The Rosewood KILN is designed to work when your guitar is placed in supine position, no other. Both ways leave your guitar in an upright stance. The Rosewood KILN uses heat and warm air rises up vertically. Guitars in upright stance would mean the heat from the Rosewood KILN would rise to warm up other areas than the areas about the bridge (which is the important area to receive treatment). Therefore, it is not recommended to place your guitar on upright stance if you are going to dehumidify your guitar with the Rosewood KILN.
  • Q8: How hot is the Rosewood KILN?
    Generally, wood glue looses it strength when heated to 60˚C to 65˚C. The Rosewood KILN is carefullycalibrated to warm up your guitar. The operating temperature ranges from 48˚C to 55˚C.
  • Q9: Would using the Rosewood KILN cause glued joints within my guitar to dislodge?
    NO. If the Rosewood KILN is operated as per instructions in its manual, your guitar would only be dehumidified, never damaged. Heat trapping may lead to unintended outcomes. Read Q6.
  • Q10: Can I use the Rosewood KILN on any guitars?
    The Rosewood KILN is designed for regular acoustic guitars and classical guitars. Using the Rosewood KILN on small body guitars or ukuleles are not recommended. Examples of small body guitars; Baby Taylor, GS-Mini, Martin D Jr, Ed Sheeran types.
  • Q11: Does purchasing a Rosewood KILN comes with a compatible power adapter?
    YES. The retail price of SGD $219.00 includes a compatible power adapter.
  • Q12: How do I get one?
    Just drop an email to or send a text to this mobile contact +65 9873 5980. You could cash & carry at GP Workshop or have it mailed to you by adding a handling fee of SGD $12.00. Looking forward to hear from you.
  • Q13: Do you ship overseas?
    Yes. Shipping costs would be advised once the destination country is provided.
  • Q14: Does the Rosewood KILN carry automated features like power cut-off, temperature display, heat limit, etc?"
    NO. This would be the early version that was to be made from polycarbonate material. This polycarbonate version is not available for sale. The Rosewood KILN and the polycarbonate versions shared the exact wood drying principles thus the Rosewood KILN is equally effective and efficient on purging excessive wood moisture from your guitars.
